Problem

The perimeter of a rectangle is 24 meters. The width is 6 meters. What would the length be?

2

Step

The perimeter(p) of a rectangle is

24 mtrs.

3

Step

The width(w) of a rectangle is

6 mtrs.

4

Hint

To find the length(l) of a rectangle is

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

5

Step

Substitute the values by using length formula

\$l = (24 / 2) - 6\$

6

Step

After division, we get

l = 12 - 6

7

Step

After subtraction, we get

6

8

Solution

Then the length of a rectangle is 6 mtrs.
