Step-by-step explanation:

a=7+3+7=17

b=3

h=8

area=(1/2)(17+3)(8)=80

Answer:

80 square units

Step-by-step explanation:

Area of a trapezoid:

A = 1/2 (base+base)h

A = 1/2 (3 + 17)8

= 1/2(20)8

= (10)8

= 80

The top part is 3 and the bottom part is

7+3+7, which is 17.

Average the bases and then × height.
