Answer» Side of the Square field (a) = 16 m Area of the square field = a2 = 16 m x 16 m = 256 m2 (i) Each of its sides increased by 4 m New side = (16+4) m = 20 m New area of the square field = (a)2 = 20 m x 20 m = 400 m2 (ii) Each of its side is double New side = 16 m x 2 = 32 m New area of the square field = (a)2 = 32 m x 32 m = 1024 m2 |
