​

Answer 1

The length is of 59 cm.

Explanation:

Perimeter of a rectangle:

The perimeter of a rectangle with width w and length l is given by:

`P = 2(w + l)`

Width of 49 centimeters and a perimeter of 216 centimeters:

This means that
`w = 49, P = 216`

The length is cm.

We have to solve the equation for l. So

`P = 2(w + l)`

`216 = 2(49 + l)`

`216 = 98 + 2l`

`2l = 118`

`l = (118)/(2)`

`l = 59`

The length is of 59 cm.
