Question

the length of a rectangle is 15m more than its breadth.if perimeter of rectangle is 80 m,find the dimensions of the rectangle​

Answer 1

Answer:

breadth = 12.5m, length =27.5m.

Step-by-step explanation:

let the breadth be X m, length be (x+15) m.

then,

perimeter= 2(l+b).

80 m= 2(x+15+x).

80m= 4x+30.

4x=80m-30m

4x=50m

x=50/4

x=12.5m.

therefore breadth is 12.5m, length is (x+15) =(12.5+15) =27.5.

hope it's useful mark me as brainliest give thank also.....
