A square figure has four equal sides.

Area of the square is A = (side)∙(side) sq unit = (side)2 sq unit

03

– Find the area of the square with side length 9 meter  

The formula for area of square is A = (side)∙(side) sq unit = (side)2 sq unit

Here side = 1.5 cm

Area = (side)2 = 1.52  =  1.5  ·  1.5  =  2.25 sq cm.
