Question

What is the area of trapezoid ABCD?

Enter your answer as a decimal or whole number in the box. Do not round at any steps.

Answer 1

37.5

Explanation:

Area= (Base1+base2)/2 *height

Base 1=b

Base 2=c

height=h

a=h(b+c)/2

h= line AB

Line AB has length
`√(4^2+3^2)=5` using the distance formula

h=5

c= 10

b=5

a=5(10+5)/2=37.5
