Question

The perimeter of a rectangle garden is 43.8 feet. It's length is 12.4 feet. What is it's width?A. 15.7 ftB. 19.0 ftC. 9.5 ftD. 6.2 ft

Answer 1

The perimeter of a rectangle is given by the formula:

`\text{Perimeter}=2\cdot\text{length}+2\cdot\text{width}`

If the perimeter is 43.8 and the length is 12.4, we can find the width:

`\begin{gathered} 43.8=2\cdot12.4+2\cdot\text{width} \\ 2\cdot\text{width}=43.8-24.8 \\ 2\cdot\text{width}=19 \\ \text{width}=(19)/(2)=9.5 \end{gathered}`

The width is 9.5 feet, therefore the answer is C.
