a.18 ft
b.41 ft
c.36 ft
d.9 ft

C)

Step-by-step explanation:

To find area, You use the equation (Length × Width). If you need to find the perimeter By using the Area, You need to Divide one of the Equal Sides, since it is a square you can use either length or width, So Since it is a square, You Can also use the Square Root method. Square root is basically Dividing the number by the number it was multiplied by.

EX:

9 × 9 = 81

because

81 ÷ 9 = 9

So, If both the Length and width are 9, You add them together to get eighteen. Though since it's a square, You Can't only Count The Half of the Shape, So you multiply that by two, Leaving you with 36
