Example Question #51 : Geometry
The hypotenuse of a right triangle is feet; it has one leg feet long. Give its area in square inches.
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 #161 : Geometry
Which of the following is equal to the area of a rectangle with length meters and width meters?
Multiply each dimension by to convert meters to centimeters:
Multiply these dimensions to get the area of the rectangle in square centimeters:
Example Question #2 : How To Find The Area Of A 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 ?
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 #51 : Geometry
A trapezoid has a height of inches and bases measuring inches and inches. What is its area?
Use the following formula, with :
Example Question #241 : Ssat Middle Level Quantitative (Math)
What is the area of a triangle with a base of and a height of ?
The formula for the area of a triangle is .
Plug the given values into the formula to solve:
Example Question #52 : Geometry
Find the area of a square with side length 1.
To solve, simply use the formula for the area of a square. Thus,
Example Question #53 : Geometry
Find the area of a triangle with height 6 and base 3.
To solve, simply use the formula for the area of a triangle.
Given the height is 6 and the base is 3, substitute these values into area of a triangle formula.
Thus,
Example Question #55 : Geometry
What is 60% of the area of the above square?
The area of a square, it being a rhombus, is the product of the lengths of its diagonals. The diagonals are of the same length, so both diagonals have length 8, and the area of the square is
.
60% of 32 is equal to 32 multiplied by , which is
.
Example Question #56 : Geometry
A circle has radius 12. Which of the following gives 40% of the area of this circle?
The area of a circle with radius is
.
The radius of the circle is, so the area is
.
40% of this is
Example Question #54 : Geometry
A rectangle measures six feet in width and four and one-half feet in height. Give its area in square yards.
81 square yards
3 square yards
9 square yards
243 square yards
3 square yards
Convert each dimension from feet to yards by dividing by conversion factor 3:
Their product is the area in square yards:
.
