Question

The sides of a rectangle are in the ratio of 4:5. Find its sides if the perimeter is 90 cm.

Answer 1

Let sides be x

Then sides = 4x and 5x

Now perimeter = 90

2(4x+5x)= 90

9x= 45

X= 5

SO SIDES ARE 20 CM &25 CMans

Answer 2

Answer:

Step-by-step explanation:

Let the length and breadth of the rectangle be 4x and 5x

It is given that perimeter of the rectangle is 90

2( 4x +5x) =90

2(9x)=90

9x=45

x=5

So the sides are 4×5=20cm and 5×5=25cm
