Question

The length of a rectangular park is 15 m more than its breadth . lf the perimeter of the park is 170
metres , find the dimensions of the park

Answer 1

Answer:

Step-by-step explanation:

Let length be l and breadth be b

Given : l=15+b

Perimeter of the rectangle is 2(l+b)=170

2(15+b+b)=170

2(15+2b)=170

15+2b=170/2

15+2b=85

2b=85-15

2b=70

b=70/2=35

Breadth, b=35m

Substitute b in l=15+b

l=15+35=50

Length, l=50m
