Question

the perimeter of a squared field is 60m find its area

Answer 1

Answer:

perimeter = 4a

60 = 4a

a = 15 m

area = a²

= 15²

= 225 m²

Answer 2

Answer:

Perimeter of a square = 60 m

(i) Perimeter of a square = 4 x side

60 m = 4 x side

60/4 = side 4

∴ side = 15 m

(ii) Area of square = (side)² = (15 m)²

= 15 m x 15 m

= 225 m²

(iii) Increased each side = 2 m

Side of square = 15 m

New length of side = (2m + 15m)

= 17 m

∴ New Area of square = (17m)² = 17m x 17m = 289 m²
