Question

the side of a rectangle are in the ratio 5 : 4 and its perimeter is 9cm find the length and breadth

Answer 1

Answer:2 and 2.5 cm

Step-by-step explanation:

Let the sides be 4x and 5x

Perimeter = 2(l+b)

9=2*9*x

x=1/2

So the, sides are 2cm and 2.5cm

Answer 2

let
The length (L) =5x
The breadth (B)=4x

Perimeter=9cm

perimeter=2 (L+B)
9 =2(5x+4x)
9 =9x*2
x=9/18cm
therefore, length=5 (1/2)=2.5cm
breadth=4 (1/2)=2cm
