Question

The perimeter of a rectangular red sticker is 14 millimeters. The sticker is 4 millimeters wide. How tall is it?

Answer 1

3 millimeters

Explanation:

The formula for finding perimeter: 2W+2L=P

W= width

L= length

P= Permiter

So just substitute the numbers in the equation

4 millimeters is the width

14 millimeters is the perimeter

So this is your equation

2*4+2L=14

8+2L=14

Subtract 8 from both sides

2L=6

Divide both sides by 2

L=3

So your length is 3 millimeters

To check:

(2*4)+(2*3)=14

8+6=14

14=14
