You are making rectangular posters 24 in. by 15 in. How many square feet of material will you need for 6 posters?

24in=2ft

15in=1.25ft

2ft*1.25ft=area of 1 poster=2.5 sq feet

(2.5 sq ft)*6 posters=15 square feet of material.

To calculate the amount of material needed for the posters, we need to find the area of one poster and then multiply it by the number of posters.

The formula for finding the area of a rectangle is:

Area = Length × Width

Given that the length of the poster is 24 inches and the width is 15 inches, we can calculate the area:

Area = 24 in × 15 in

Before we calculate the area, let's convert the measurements from inches to square feet, as the final answer is required in square feet.

We know that 1 square foot is equal to 144 square inches.

So, let's convert the measurements:

Length in square feet = 24 in ÷ 12 in/ft
Width in square feet = 15 in ÷ 12 in/ft

Now we can calculate the area in square feet:

Area = (Length in square feet) × (Width in square feet)

Now that we have the area of one poster in square feet, we can multiply it by the number of posters to find the total amount of material needed:

Total Material = Area (in square feet) × Number of Posters

Plug in the values and perform the calculation:

Area = (24 in ÷ 12 in/ft) × (15 in ÷ 12 in/ft)
Area = (2 ft) × (1.25 ft)
Area = 2.5 square feet

Total Material = 2.5 square feet × 6 posters
Total Material = 15 square feet

Therefore, you will need 15 square feet of material for 6 posters.
