Question

The sides of a rectangle are x cm and 5 cm. Its perimeter is 24 cm. Find the
value of x.​

Answer 1

Answer:

Perimeter of Rectangle=2(l+b).

24= 2(x+5).

2x+10=24.

2x=14.

x=7.

Hence, The sides of a rectangle are 7 cm and 5 cm.

Answer 2

Given= sides of a rectangle = x cm and 5 cm

Perimeter of a rectangle = 24 cm

Perimeter of a rectangle = 2(l+b)

24 = 2(x+5)

24/2 = x+5

12 = x+5

x = 12-5

x = 7

Therefore,the value of x = 7 cm .
