Question

The perimeter of a rectangular painting is 326 centimeters. If the length of the painting is 88 centimeters, what is its width?

Answer 1

Answer:

The width is 75 cm

Step-by-step explanation:

Perimeter is L+L+W+W aka 2L+2W

L=length     W=width

326=2(88)+2W

Solve for W

326=176+2w

150=2w

w=75

Answer 2

Answer:

Width = 75 cm

Step-by-step explanation:

l = 88 cm

Perimeter = 326 cm

2l +2w = 326

2*88 + 2w = 326

176 + 2w = 326

Subtract 176 from both sides

         2w = 326 - 176

         2w  = 150

Divide both sides by 2

           w = 150/2

           w = 75
