Question

The area of a rectangular painting is 8245 cm2. If the width of the painting is 85 cm, what is it's length?

Answer 1

We know that the painting is rectangular, which area is

`A=w* l`

Where A = 8245 cm2, and w = 85 cm. Let's solve for l

`\begin{gathered} 8245=85* l \\ l=(8245)/(85)=97 \end{gathered}`

Hence, the length is 97 centimeters.
