Question

17 A gardener has to lay a grass lawn, leaving space for 80 cm wide bed of flowers along the inside edge
of a square garden with an area of 72.25 m2. What will be the area of the grass lawn?

Answer 1

Answer:

area of square =side^2

100 cm =1 m

80 cm =0.80 m

72.25 m=0.80×0.80

72.25 m= 0.64 m

72.25/0.64

112.89 m
