Question

The length of a field is 15 metres mor than its width. Find its length breadth and area if its perimeter is 240 metres
​

Answer 1

Step-by-step explanation:

Let the breadth be x

Length=x+15

Perimeter=240m

Perimeter=2(l+b)

240=2(x+15+x)

120=2x+15

2x=105

x=52.5m

Breadth=52.5m

Length=67.5m

Area=l×b

52.5×67.5

=3543.75m2
