Step-by-step explanation:

Given : perimeter of rectangle = 180cm and the sides are in the ratio 4:5

Solution,

Let the side lengths be 4x and 5x

Now the perimeter of rectangle = 2(l + b)

Thus,

=> 180 = 2(5x + 4x)

=> 180 = 2(9x)

=> 180 = 18x

=> x = 180/18

=> x = 10

Therefore,

The length of sides are,

=> 4x = 4 × 10 = 40 cm and

=> 5x = 5 × 10 = 50 cm

Answer 2

Answer:

4:5=180

5=4/180

5=45

=45-5

=40
