2. Find the length of a side of a square if its area is:

a. 81 square inches
b. cm
c. 0.49 square units
d. m² square units

Answer 1

9 inches ; 0.7 units ; m units

Explanation:

The area of a square is give as :

The square of the side length of the square ; that is ;

Area of square = s² ;

Where s =! Side length of the square

Hence ;

A square with area = 81 in²

Length of its side = sqrt(81) = 9 inches

Area of square = 0.49 unit²

Length of its side = sqrt(0.49) = 0.7 units

Area of square = m² unit²

Length of its side = sqrt(m²) = m units
