Question

the sides of a rectangle are in the ratio 5:4 and its perimeter is 90 cm. find its length and breadth.​

Answer 1

Answer:

Answer:

Its length and breadth are 25 cm and 20 cm respectively.

Step-by-step explanation:

The sides of a rectangle are in the ratio 5:4

Let the ratio be x

so, Length = 5x

Breadth = 4x

Perimeter of rectangle =  

                                     =  

                                     =

Step-by-step explanation:

Answer 2

Step-by-step explanation:

Perimeter of rectangle = 2(length+breath)

length+breath = 5x+4x

90 = 2(5x+4x)

90/2 = 9x

45 = 9x

x = 5

length = 5*5 = 25

breath = 4*5 20
