Area of road = 105*105-100*100=1025m ^2
Area of road = area of garden with road - area of garden
= 105*105 - 100*100

Answer 2

Given inner side of square park, s = 100 cm
Area of inner square = 1002 = 10000 sq cm
width of path, w = 5 m
Outer side of square = 100 + 10 = 110 cm
Area of outer square = 1102 = 12100 sq cm
Area of path = 12100 - 10000 = 2100 sq cm
Cost of cementing at the rate of Rs 250 per 10 sq m = Rs 250 × 210
= Rs 52500
