A designer wants to estimate the area of a trapezoid-shaped stage. Each square represents one square foot. The designer decides to find the area by composing a rectangle. What is the length of the base of the rectangle in feet?(1 point)
The box that the trapezoid is in is 15 squares long.
Since the trapezoid is composed of a rectangle and a right triangle, you can calculate the length of the base of the rectangle by subtracting the length of the triangle from the total length of the box.
The trapezoid is made up of a rectangle and a right triangle.
The rectangle has a base length of 15 squares.
To find the length of the right triangle, you need to find the difference between the two parallel sides of the trapezoid which are the base of the rectangle and the top base of the trapezoid.
Let's say the top base of the trapezoid is 10 squares long.
Subtract the length of the top base from the length of the box to find the length of the right triangle:
15 - 10 = 5
Therefore, the length of the base of the rectangle in feet is 5 feet.
