Question

Help me write an expression to find perimeter.

Answer 1

Answer:

Perimeter, $P=\dfrac{2}{5}(5x+14)$

Step-by-step explanation:

We have, a hand woven rectangular rug measures x ft long and $2\dfrac{4}{5}\ ft$ wide. For a rectangular shaped object, perimeter is equal to the sum of all sides. If l is length and b is width, then

Perimeter, $P=2(l+b)$

We have, l = x ft and b = $2\dfrac{4}{5}\ ft=\dfrac{14}{5}\ ft$

So,

$P=2(x+\dfrac{14}{5})$

or

$P=\dfrac{2}{5}(5x+14)$
