Question

The diagram of a rectangular canvas is 4 1/2 by 2 if the paint to cover the canvas costs 4.50 what is the price per square foot

Answer 1

Answer:

The price per square foot is $0.50

Step-by-step explanation:

step 1

Find the area of the canvas

The area of the rectangular canvas is equal to

$A=LW$

we have

$L=4\frac{1}{2}\ ft= 4+\frac{1}{2}=\frac{4*2+1}{2}=\frac{9}{2}\ ft$

$W=2\ ft$

substitute

$A=(\frac{9}{2})(2)=9\ ft^2$

step 2

Find the price per square foot

Divide the cost by the area

so

$\frac{4.50}{9}=\ 0.50\ per\ square\ foot$
