Question

A square patio has an area of 121 square yards. What is the length of this patio?

Answer 1

A=s^2 121=s^2 Square root of 121=s S=11 The length is 11 yards.

Answer 2

we now that the patio is shaped as a square

Area of a square is equal to :  a x a

so , a x a  = 121

a^2   = 121

a    = $\sqrt{121}$

a = 11

The length of the patio would be 11

hope this helps
