Question

the lenght of a rectangular park is thrice its breadth.if the perimeter of the park is 168 metres,find its dimensions​

Answer 1

Answer:

let breadth of A rectangular park be b m

Then length will be = 3b m

Perimeter of the park = 168 m

2(length+breadth) = 168

2( 3b + b ) = 168

2(4b) = 168

8b = 168

b=168/8

b=21 m

Then, l=3×21

l=63 m
