Question

So like I need help on this,

Choose the graph that represents the figure and classify it. Then find the area.


D(-1, -1), E(-1, 3), F(2, 4), G(2, -3)

Answer 1

• Trapezoid with the area 16.5 unit²

Explanation:

Plotted the given points to find out the figure is trapezoid.

Area formula for trapezoid:

• A = 1/2(b₁ + b₂)h

The length of the bases:

• b₁ = DE = 3 - (-1) = 4
• b₂ = FG = 4 - (-3) = 7

h is the horizontal distance between the bases:

• h = 2 - (-1) = 3

The area is:

• A = 1/2(4 + 7)(3) = 16.5 unit²
