Example Questions

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:

Example Question #392 : Ssat Middle Level Quantitative (Math)

Trapezoid

The above diagram depicts a rectangle  with isosceles triangle . If  is the midpoint of , and the area of the orange region is , then what is the length of one leg of  ?

Possible Answers:

Correct answer:

Explanation:

The length of a leg of  is equal to the height of the orange region, which is a trapezoid. Call this length/height .

Since the triangle is isosceles, then , and since  is the midpoint of , . Also, since opposite sides of a rectangle are congruent, 

Therefore, the orange region is a trapezoid with bases  and  and height . Its area is 72, so we can set up and solve this equation using the area formula for a trapezoid:

 

This is the length of one leg of the triangle.

Example Question #1 : How To Find The Area Of A Trapezoid

A trapezoid has a height of  inches and bases measuring  inches and  inches. What is its area?

Possible Answers:

Correct answer:

Explanation:

Use the following formula, with :

Example Question #23 : Area Of A Triangle

What is the area of a triangle with a base of  and a height of ?

Possible Answers:

Correct answer:

Explanation:

The formula for the area of a triangle is \dpi{100} Area=\frac{1}{2}\times base\times height.

Plug the given values into the formula to solve:

\dpi{100} Area=\frac{1}{2}\times 12\times 3

\dpi{100} Area=\frac{1}{2}\times 36

\dpi{100} Area=18

Example Question #1232 : Concepts
