Question

the length and breadth of a playground are 80m and 35m respectively. find the cost of levelling it at Rs 4.50 per square metre

Answer 1

Length = 80m

Breadth = 35m


Area of playground = 80 m × 35m

= 2800m²

Cost per m² = Rs 4.50

Cost for 2800m² = 2800 × 4.50

= Rs 12600

Answer 2

area = L × B
= 80 × 35 = 2800 sq.m
cost of 1 sq.m = 4.5 Rs.
cost of 2800 sq.m = 4.5 × 2800
= 12600 Rs. ANSWER.
