Question

Deanna knows that the floor in her kitchen is a square with an area of 169 ft2. The perimeter of her kitchen floor is found by adding the lengths of all its sides. What is the perimeter of her kitchen floor? Explain how you found your answer.

Answer 1

52m

Explanation:

Area of the square floor = 169 m²

• For a square with each side 's' , area will be s². Similarly , for a square with area 'a' , length of each side will be √a.

So,

Length of each side of floor = √169 = 13m

• For a square with each side 's' , its perimeter will be 4s.

Hence ,

Perimeter of the kitchen = 13 × 4 = 52m

Answer 2

52 ft

Explanation:

area of a square is l x w. all sides are equal so the l = w

A = 169 ft^2 so each side is the square root of 169 which is 13 ft

perimeter of the floor would be all four sides added or length of 1 side multiplied by 4 since they are all equal

Perimeter = 13ft × 4 = 52 ft

so:
