Question

2.
The length of the rectangle is 5 cm more than its breadth. Its perimeter is five
times its breadth. Find the length and breadth of the rectangle.​

Answer 1

Answer:

width=10cm

length=15cm

Step-by-step explanation:

let width be x

perimeter=2(l+b)

5x=2(x+5+x)

5x=2(2x+5)

5x=4x+10

5x-4x=10

x=10

width=10cm

length=15cm

Answer 2

Answer:

let breadth be x

lenght = x + 5

perimeter = 5x

perimeter = 2(l + b) = 2( x + 5 + x)

                 = 2(2x + 5)

                 =4x + 10

4x + 10 = 5x

10 = 5x - 4x

x = 10

x + 5 = 15

therefore

lenght = 15cm

breadth = 10cm
