Find the area of the trapezoid. a. 675 ft2 b. 337.5 ft2 c. 187.5 ft2 d. 150 ft2

B.

Step-by-step explanation:

The area of trapezoid is given by :-

, where a and b are the parallel sides and h is the height.

From the given picture, we have

Height (h) = 15 ft

a =  20 ft.

b =  25 ft.

Then , the area of trapezoid is given by :-

Hence, the area of trapezoid is

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
