Problem

The rectangle has a perimeter of 86 meters and a length of 25 meter.Find the width.

Step

Perimeter (p) of rectangle is given,

40 cm

Step

Length of rectangle is given

p = 4s

Step

We need to determine the width value in this context.

Formula

Perimeter of rectangle is

p = 2(l + w)

Step

Substitute the values

86 = 2(25 + w)

Step

Subtract 50 on both sides

86 = 50 + 2w

86 - 50 = 2w

2w = 36

Step

Divide 2 on both sides of the equation

\$(2w)/2\$ = \$36/2\$

Step

The width of a rectangle is 18 meters.
