Answer:

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.
