Problem

The perimeter of a rectangle is 16 meters. The length is 6 meters. What would the width be?

2

Step

The perimeter(p) of a rectangle is

16 mtrs

3

Step

The length(l) of a rectangle is

6 mtrs

4

Hint

To find the width(w) of a rectangle

\$p = 2(l + w)\$
\$l = (p / 2) - w\$

5

Step

Substitute the values by using width formula

\$w = (16 / 2) - 6\$

6

Step

After division, we get

w = 8 - 6

7

Step

After subtraction, we get

2

8

Solution

Then the width of a rectangle is 2 meters.
