Question

The area of a rectangular park is 800m and it's breadth is 40m. Find the cost of levelling it at the rate of ₹5 per square meter. Also, find the distance covered by a boy in going 4 times round the park. ​

Answer 1

Answer:

The area of rectangular park = 800 m

Cost of levelling = 5 * 800 m

= ₹ 4000

Area of park = 800 m

Boy round the park = 4 round

= 4 * 800 = 3200 m or 3 km 200 m

Answer 2

Answer:

Area of park=800

${m}^{2}$

cost of levelling 1 sq meter=₹5

therefore, cost of levelling park=₹5×800

=₹4000

it's breadth=40m

therefore, it's length=800/40=20m

perimeter of field=2(l+b) =2(20+40) m=2×60m=120m

distance covered by boy in going 4 times round the park=4×120m=480m
