Question

The length and breadth of a playground are 70.8m and 42.7m.find the cost of levelling it at the rate of 2 square meter .also find the distance coveted by a boy to take three rounds of the field

Answer 1

$<u>Dimensions of Playground</u>$

Length = 70.8 m

Breadth = 42.7 m

Area of playground = Length × Breadth

= 70.8 × 42.7

= 3,023.16 m²

$<u>Cost of levelling 1 m² = Rs. 2</u>$

Cost of levelling 3,023.16 m² = Rs. 2 × 3,023.16

= $<b>Rs. 6,046.32</b>$

Circumference of playground = $<u>2 ( Length + Breadth )</u>$

= 2 ( 70.8 + 42.7 )

= 2 × 113.5

= 227 m

If a boy take one round, he covers $<u>227 m.</u>$

After taking 3 rounds, distance covered by him –

= 3 × 227

= $<b>681 m</b>$
