Question

Sides of a rectangle are 4:5 find its sides if the perimeter is 180

Answer 1

Answer:

80. 100

Step-by-step explanation:

4x+5x=180

9x=180

x=180/9

x=20

4x=80

5x=100

Answer 2

Step-by-step explanation:

The ratio of the measurements of the sides of the rectangle is 4:5

Let the measurements be 4x and 5x

Perimeter of a rectangle = 2(l+b)

Given perimeter = 180

therefore , 2(l+b)=180

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

=>2(9x)=180

=>18x=180

=>x=180/18

therefore ,x =10

the measurements are 4×10 and 5×10

=40 and 50 units
