Hi Cami,
Let the length of a rectangle = L feet
and the width of a rectangle = W feet
Use the following rectangle formulas to solve this problem
Area of a rectangle ( A) = length x width
Perimeter of a rectangle ( P) = 2 ( length + width )
Now substitute A = 65 feet, P = 36 feet, length = L feet and width = W feet in the above formulas
65 = L x W 36 = 2 ( L + W )
13 x 5 = L x W ---- 1 (65 = 13 x 5) 18 = L + W
13 + 5 = L + W ----- 2 (18 = 13 + 5 )
From 1 and 2 equations L = 13 feet and W = 5 feet
so, the dimensions of the tent are 13 feet length and 5 feet width.
Hope this is helpful.
