Answer:

20 square yards

Explanation:

Perimeter is l + l + w + w or 2l + 2w

Because these rectangles have the same perimeter they are equal.

Set them equal in an equation

2(9) + 2(3) = 2(l) + 2(2)

Simplify

18 + 6 = 2l + 4

24 = 2l + 4

Subtract 4 from both sides to isolate the variable l

20 = 2l

Divide both sides by 2

10 = l

So the length of the purple triangle is 10 yd

Area = l x w

Substitute in the values of the purple triangle

Area = 10 x 2

Area = 20 square yards
