Question

Alex is making 12 pennants for the school fair. The pattern he is using to make the pennants is shown in the figure. The fabric costs $1.25 per square foot. How much will it cost Alex to make 12 pennants?​

Answer 1

Answer:

It will cost Alex $52.5 to make 12 pennants

Step-by-step explanation:

The area of the pennant is the area of the rectangular portion plus the area of the triangular portion.

$=1\times 3 +\frac{1}{2}\times 1\times 1$

$Area=3+\frac{1}{2} ft^2$

$Area=3.5 ft^2$

The area of 12 pennants

$=12\times 3.5ft^2$

$=42ft^2$

If the fabric for the pennants costs $1.25 per square foot, then;

42 square feet will cost $1.25\times 42=52.5$ dollars.
