Lesson Steps
| Step | Type | Explanation | Answer |
|---|---|---|---|
1 |
Problem |
The rectangle’s length is 14ft and its perimeter is 36ft. What is its width? |
|
2 |
Step |
The perimeter(p) of a rectangle is |
36 ft. |
3 |
Step |
The length(l) of a rectangle is |
14 ft. |
4 |
Hint |
To find the width(w) of a rectangle |
p = 2(l + w) w = \$p / 2\$ - l |
5 |
Step |
Substitute the values by using width formula |
w = \$36/2 - 14\$ |
6 |
Step |
After division, we get |
w = 18 - 14 |
7 |
Step |
After subtraction, we get |
4 ft |
8 |
Step |
Then the width of a rectangle is 4 ft. |
