Question

5. The perimeter of a rectangle is 76 cm. If its sides are in the ratio 11:8, find its sides​

Answer 1

Step-by-step explanation:

Let the length and breadth be 11a and 8a

Then, perimeter=2(11a+8a)=76

11a+8a=38

19a=38

a=2

Hence, your sides are 22 and 16

Answer 2

Step-by-step explanation:

Let the length be 11x

and breadth be 8x

perimeter=2(l+b)

76=2(11x+8x)

76=22x+16x

38x=76

x=76/38

x=2

length=22cm

breadth=16cm
