hi

aim :Find the perimeter of a rectangular park if its length is 200 m and area is 4800 m square. find cost of livelling the park at the rate of 1.35 per m square.

lenght = 200m

area  = 4800 m ²

area  = l*b

so,

4800 = 200 * b

b = 4800/200

b = 24 m

braedth is 24 m

now perimetr of rectangle

= 2(l+b)

=2(200+24)

= 2(224)

= 448m


now cost of cost of livelling the park at the rate of 1.35 per m square.

1 m² =  1.35 rs

448 m² = 4800 *1.35

=  6480 rs
