Question

The length of a rectangle is six times its width. If the perimeter of the rectangle is 98 yd , find its area.

Answer 1

Let's call the rectangle u

The sides of the rectangle are a and b:

Then is \[u = 2 \cdot (a+b)\]

And \[a=6 b\]

\[u = 2 \cdot (6b+b) = 14 \cdot b\]

SO the width is 7 and the lengt is 42

Answer 2

And the area is 7x42?

Answer 3

Yes of course, what else?

Answer 4

OoohThanks :)
