The glass in Lee’s window needs replacing. It is 30 inches wide and 24 inches long. What is the area (A) of the glass Lee should buy?
A. A = (2 × 30) + (2 × 24) = 108 in.
B. A = 30 × 24 = 720 in2
C. A = 2 × (30 + 24) = 108 in2
D. A = 30 + 24 = 54 in.
Area = length times width
Which of your choices shows that calculation?
Thanks, I wasn't so sure at first, I guess I just forgot
To find the area (A) of the glass Lee should buy, we need to multiply the width by the length. In this case, the width is 30 inches and the length is 24 inches.
So, option B is the correct answer: A = 30 × 24 = 720 in².
To arrive at this answer, you simply multiply the width (30 inches) by the length (24 inches) to find the area in square inches.
