Question

what is the area and perimeter of the figure with the given vertices? (7,8) , (-5, -8) , (7,-8) , (-5,8)?

Answer 1

• perimeter: 56 units
• area: 192 square units

Explanation:

We assume you're interested in the convex polygon, so the given vertices are not listed in order around the figure.

The figure is 12 units by 16 units, so has a perimeter of ...

P = 2(L +W)

P = 2(16 +12) = 56 . . . . units

and an area of ...

A = LW

A = (16)(12) = 192 . . . . square units
