Question

the length of a regtangle is 10 m more than the breadth.If the perimeter of the retangle is 140m.find the lenght and breadth​

Answer 1

Step-by-step explanation:

let take breadth of rectangle=x m.

then length=(x+10) m.

perimeter of rectangle=2(length+breadth)=140m.

2(x+x+10)=140

2(2x+10)=140

2x+10=140/2

2x+10=70

2x=60

x=30

so the breadth of rectangle=30m.

length of rectangle =40m.

I hope it helps
