Question

the length and breadth of a rectangle arw in the ratio 5: 3 . if its perimeter is 80 cm , then its length is.​

Answer 1

Answer:

25cm

Step-by-step explanation:

let constant be x

so ur length is 5x and breadth is 3x

perimeter =2×(l+b)

=2×8x

80 =16x

80/16=x

5=x

length is 5x which will be 5×5 =25cm

hope it helps you mate

Answer 2

Given ratio=5:3

So, l=5x and b=3x

Perimeter of rectangle= 2(l+b)

 80=2(l+b)

80/2=5x+3x

40=8x

x=40/8

x=5

Therefore, Length=5*5=25
