Question

I need help determininh the area and perimeter of the trapezoid

Answer 1

Area = ?

Perimeter = ?

-Calculate the length of the left side

20 = 16 + c^2

20 - 16 = c^2

c^2 = 4

c = 2m

-Left side

x = 8 - 5 - 2

x = 1 m

a^2 = 16 + 1

a = squared root 17

Perimeter = 21.6 m

area = (5 x 4) + (4 x 2/2) + (4 x 1/2)

= 20 + 4 + 2

area = 26 m^2

`\text{Perimeter = 5 + 8 + }\sqrt[]{20\text{ }}+\text{ }\sqrt[]{17}`
