Question

A rectangle has a width of centimeters and a perimeter of centimeters. What is the rectangle's length?

Answer 1

Answer: We have to find the length and the width of the rectangle provided that the perimeter is 44m:

`\begin{gathered} P=2L+2W=44\rightarrow(1) \\ \\ \end{gathered}`

Therefore using the information provided and plugging in the equation (1) we get the following answer:

`\begin{gathered} P=2L+2W=44 \\ \\ L=2W+4 \\ \\ P=2(2W+4)+2W=44 \\ 6W=36\rightarrow W=(36)/(6)=6 \\ \\ W=6m \\ \\ L=(44-2W)/(2)=(44-12)/(2)=16 \\ \\ L=16m \end{gathered}`
