Question

The perimeter of a rectangle is 34 cm and one of its side is 7 cm .What is the length of other​

Answer 1

Answer:

let the length of other side be x

perimeter of rectangle = 2 ( l+b )

34 = 2 ( x+ 7 )

34 = 2x + 14

34- 14 = 2x

20 = 2x

x = 10

Answer 2

Answer:

Perimeter of a rectangle = 34

Breadth of a rectangle = 7 cm

length of rectangle = ?

Also perimeter of rectangle =2(l+b)

2(l+b) = 34

2(l+7) = 34

14 + 2L = 34

2L= 20

L= 10
