A plan for a playground is a square shape witha perimeter of 32 units. What would be the area of this playground in square units? Explain how you get the answer using pictures, numbers, or words

P = 4 * s
32 / 4 = 8 units on each side
A = s * s
A = 8 * 8
A = 64 square units

dear judy,
When you are finding the perimeter of any shape and it doesn't give you the measure like inches, then always put units. When you are finding the area of any figure and it doesn't give you the measures like inches, then use square units.
In this case the answer would be
32/4= 8
8*8=64
the answer is 64 square units

Adding to my answer, if you are finding the area of any figure, even if it gives you the measure like inches, always put square before the measure.
like:
13 square inches
145 square cm.
