the perimeter of a rectangle is 222 millimeters if the length of the rectangle is 60 millimeters what is the width of the rectangle

Sagot :

The perimeter is going to be 2x+2y=222 (x being length and y being height.)

We know our length, x, so plug it in.

2(60)+2y=222
120+2y=222

Subtract.

2y=102

Divide.

y=51

Your width is 51mm.

Perimeter is when you add all of the sides together. To solve this problem, you would double 60 because their are 2 sides of the length. Then you would subtract 222 and 120 to get 102. Then you would divide that by 2 to get 51mm as the answer for the width.
