Question

Trapezoid ABCD is graphed in a coordinate plane. What is the area of the trapezoid?

Answer 1

BC=-1 to 3=4
B to AD=2 to -2=4
4x4=16
AB=-3 to -1=2
2x4x1/2=4
Triangle CD=4
Total area=16+4+4=24

Answer 2

Answer

24 square units

Explanation

The formula for getting the area of a trapezium is

Area = 1/2 h(a+b0

where h ⇒ perpendicular height

a and b ⇒ length of the parallel sides.

h = 2 - -2 = 4 units

a = 5 - -3 = 8 units

b = 3 - -1 = 4 units

Area = 1/2 × 4(8+4)

= 2×12

= 24 square units.
