Question

The perimeter of a rectangular red sticker is 26 millimeters. It is 4 millimeters tall. How wide is it?

Answer 1

It is 9 millimeters wide

Answer 2

9

Explanation:

perimeter= side+side+side+side

if we know that it is 4 millimeters tall, we know two sides are 4 millimeters tall, so we have 8. to find the sum of the last two sides, we subtract 8 from 26, which give us 18. finally, we divide by 2 to get 9, the width of the rectangle.
