Solution 12:
Side of the square field (a) = 16 m
∴ Area of the square field = (a)²
= 16 × 16 = 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 × 20 = 400 m²
(ii) Each of its side is doubled
∴ New side = 16 × 2 = 32 m
∴ New area of the square field = (a)²
= 32 × 32 = 1024 m²
