Question

the length of a rectangle exceeds width 15 cm. The perimeter of the rectangle is 100cm.Find its length and breadth

Answer 1

Answer:

let width be x

length is 15+x

Step-by-step explanation:

perimeter of rectangle is 2(l+b)

substituting

perimeter= 2(15+x+x)

perimeter= 30+ 4x

but given perimeter is 100

30+4x= 100

4x= 70

x= 70/4= 17.5 cm= width

length= 15+17.5= 22.5 cm
