Question

Katrina wants to build a fence around her square garden. Her garden has an area of 121 square feet. How much fencing will Katrina need? A. 13 feet B. 26 feet C. 39 feet D. 44 feet

Answer 1

Answer:

D. 44 feet

Step-by-step explanation:

If her garden is square, that means that to find out the length of one wall we find the square root of 121. The square root of 121 is 11. Then because the garden needs 4 walls of fencing, we multiply 11x4=44.

Answer 2

Answer:

D) 44 feet

Step-by-step explanation:

As, the area of any square = Side x side

So here let's take side as "s"

So s x s = 121 square feet

S^2 = 121

So, s = the square root of 121

So, s = 11 cm

So the length of one side of the garden = 11 cm

So all the side are equal in a square

So, to fence we need to find the perimeter

Perimeter of square = 4s

= 4 x 11

= 44 feet

Hope it helps
