Example Questions

Example Question #11 : Plane Geometry

The hypotenuse of a right triangle is 25 inches; it has one leg 15 inches long. Give its area in square feet.

Possible Answers:

Correct answer:

Explanation:

The area of a right triangle is half the product of the lengths of its legs, so we need to use the Pythagorean Theorem to find the length of the other leg. Set :

The legs are 15 and 20 inches long. Divide both dimensions by 12 to convert from inches to feet:

 feet

 feet

Now find half their product:

 square feet

Example Question #281 : Ssat Middle Level Quantitative (Math)

What is the area of a square with perimeter 64 inches?

Possible Answers:

It cannot be determined from the information given.

Correct answer:

Explanation:

The perimeter of a square is four times its sidelength, so a square with perimeter 64 inches has sides with length 16 inches. Use the area formula:

Example Question #282 : Ssat Middle Level Quantitative (Math)

The area of the square is 81. What is the sum of the lengths of three sides of the square?

Possible Answers:

Correct answer:

Explanation:

A square that has an area of 81 has sides that are the square root of 81 (side2 = area for a square).  Thus each of the four sides is 9.  The sum of three of these sides is .

Example Question #288 : Ssat Middle Level Quantitative (Math)

The length of one side of a square is . What is the square's area?

Possible Answers:

Correct answer:

Explanation:

The area of any quadrilateral is found by multiplying the length by the width. Because a square has four equal sides, the length and width are the same. For the square in this question, the length and width are .

Remember: area is always given in units2 .

Example Question #24 : Quadrilaterals

If a square has a side that is 3 yards long, what is the area in square feet?

Possible Answers:

Correct answer:

Explanation:

The area of a square is found by multiplying the length of a side by itself.

If one side is 3 yards, this means one side is 9 feet since there are 3 feet in a yard.

Since every side is of equal length, you would multiply 9 feet by 9 feet to find the area.

This results in 81 square feet, which is the correct answer. 

Example Question #161 : Plane Geometry

Find the perimeter of the trapezoid:
Question_12

Possible Answers:

Correct answer:

Explanation:

The perimeter of any shape is equal to the sum of the lengths of its sides:

Example Question #45 : Geometry

The perimeter of a square is .  Find the area.

Possible Answers:

Correct answer:

Explanation:

A square has four equal sides.  Given the value of the perimeter, divide the perimeter by four to determine each side length.

Square the side length to find the area since the area of the square is .

Example Question #1231 : Concepts

Find the area of a square in  with a side length of .

Possible Answers:

Correct answer:

Explanation:

Write the area for a square.

Convert  to inches first. One foot is .

Substitute the side.

Example Question #241 : Ssat Middle Level Quantitative (Math)

The hypotenuse of a right triangle is  feet; it has one leg  feet long. Give its area in square inches.

Possible Answers:

Correct answer:

Explanation:

The area of a right triangle is half the product of the lengths of its legs, so we need to use the Pythagorean Theorem to find the length of the other leg. Set :

The legs have length  and  feet; multiply both dimensions by  to convert to inches:

 inches

 inches.

Now find half the product:

Example Question #51 : Rectangles

Which of the following is equal to the area of a rectangle with length  meters and width  meters?

Possible Answers:

Correct answer:

Explanation:

Multiply each dimension by  to convert meters to centimeters:

Multiply these dimensions to get the area of the rectangle in square centimeters:
