Exercise 64 Page 34

Use the formula for the area of a square.

9 meters

Practice makes perfect

We have been given the area of a square and need to solve for the side length.

In order to do this, let's first recall the formula for the area of a square. A=s^2 In the formula s is the length of one side. We know that the square has an area of 81m^2. We will substitute 81 for A in the formula and then solve for s.

A=s^2

Substitute

A= 81

81=s^2

RearrangeEqn

Rearrange equation

s^2=81

SqrtEqn

sqrt(LHS)=sqrt(RHS)

s=sqrt(81)
