2 |
Step |
Given the area of rectangle is width is |
\$45(cm)^2\$ \$5\$ cm |
3 |
Formula: |
The formula for calculating the area of a rectangle is: |
Area (a) = \$Length(l) \times width(w) \$ |
4 |
Formula: |
we can rearrange the formula to solve for the length: |
Length = \$(Area) / (Width)\$ |
5 |
Step |
Substitute the values |
\$L = 45/5\$ |
6 |
Step |
After Simplification, |
\$9\$ cm |
