Question

The width of the rectangular drawing is one third the length plus 3 inches. What is the perimeter of the drawing? Write and evaluate an expression to solve the problem

Answer 1

Answer:

The expression is $P=\frac{8x+18}{3}$

Step-by-step explanation:

Given : The width of the rectangular drawing is one third the length plus 3 inches.

To find : What is the perimeter of the drawing?

Solution :

Let the length of the rectangular drawing is l=x.

The width of the rectangular drawing is one third the length plus 3 inches.

i.e. $w=\frac{x}{3}+3$

The perimeter of the drawing is $P=2(l+w)$

$P=2(x+\frac{x}{3}+3)$

$P=2(\frac{3x+x+9}{3})$

$P=2(\frac{4x+9}{3})$

$P=\frac{8x+18}{3}$

The expression is $P=\frac{8x+18}{3}$
