Question

1. marcia is building a doghouse and needs to cut plywood for the roof. plywood comes in sheets that are 48 square feet. marcia needs two squares that are each 12 square feet. how much plywood is left over?

36 square feet
12 square feet
24 square feet
60 square feet

Explanation:

Step1: Calculate total plywood needed

Marcia needs two squares each of 12 square feet. So total needed is $2\times12 = 24$ square feet.

Step2: Calculate leftover plywood

Plywood sheet is 48 square feet. Leftover is $48 - 24 = 24$? Wait, no, wait the problem says "Plywood comes in sheets that are 48 square feet. Marcia needs two squares that are each 12 square feet." Wait, wait, maybe I miscalculated. Wait, 48 - (212) = 48 -24 =24? But the options have 24? Wait no, wait the first option is 36? Wait, maybe the plywood sheet is 48? Wait no, maybe the problem has a typo? Wait no, let's recheck. Wait, maybe the plywood sheet is 48? Wait, Marcia needs two squares each 12, so total used is 212=24. Then leftover is 48-24=24? But the options have 24 as an option. Wait but let me check again. Wait, maybe the plywood sheet is 48? Wait, the problem says "Plywood comes in sheets that are 48 square feet. Marcia needs two squares that are each 12 square feet. How much plywood is left over?" So 48 - (212) = 48-24=24. So the answer is 24 square feet. Wait but let me check the options. The options are 36,12,24,60. So 24 is an option. So step1: total used = 212=24. Step2: leftover = 48-24=24.

Answer:

24 square feet (the option with "24 square feet")
