A square lawn has an area of 225 square yards. What is the length of each side?

A square is a regular polygon with four sides. It has four right angles and parallel sides. To calculate the area of a square, multiply the base by itself, which can be expressed as side * side. If a square has a base of length 8 inches its area will be 8 * 8 = 64 square inches

Area of a square is given by:

A = a2

where a = length of side

Perimeter of a square = 4a

Diagonal of a square = (a) (sqrt (2)) or 1.414 (a)

Sorry if thats wrong o. o
