Answer:
The correct option is option (B)
Yes, he will have enough poster board because 10 = 2.5 feet. Then, 2.5 x 2 = 5 square feet .
Step-by-step explanation:
1 foot = 12 inches.
Fabian needs 45 square feet of poster board for an art.
Actually, the area of the poster is 4.5 square feet.
[Since the unit of 4.5 is square feet, so it is unit of area.]
He buys a sheet of poster board with length 30 inches and a width 2 feet.
The units of length and width are not same.
So, first we need to convert the width in inches.
The length of the sheet is = 30 inches
=(30÷12) inches
=2.5 feet.
Total area of the sheet = length×width
=(2.5×2) square feet
= 5 square feet
So, the area of sheet is more than the area of poster.
Yes, he will have enough poster board because 10 = 2.5 feet. Then, 2.5 x 2 = 5 square feet .
