Question

Find the area of the trapezoid.
A. 84 ft^2
B. 94.5 ft^2
C. 72 ft^2
D. 168 in^2

Answer 1

Try breaking it up into a rectangle and triangle

Can you find the area of the triangle and the rectangle?

Answer 2

area of a triangle = 1/2 *base * height = 1/2 * 3* 8 sq feet
area of a rectangle = length * breadth = 8 *9 sq feet

Answer 3

Now add them together.

Answer 4

alternatively, you can use the formula

A = h*(b1+b2)/2

where

A = area
h = height
b1 = base #1
b2 = base #2

the two bases b1 and b2 are parallel to each other
the height is the side that's at 90 degree angles to the base
