Emily wants to plant some roses in her square lawn.

Question

If the area of the lawn is 109 square feet, estimate the maximum length to the nearest whole number, of each side of the lawn.

Answer 1

Since the shape of the lawn is square, the area is equal to the side squared.

 

109 = x²  or  x = √109 = 10.4 ft

 

       ≅ 10 ft to the nearest whole foot.
