Dalia’s living room is 12-feet long and 10-feet wide. Her dining room is also 10-feet wide. Write two equivalent expressions to represent the combined area of the two rooms. Show your work

244

Step-by-step explanation:

If each room is a square, then,

area of living room = 12*12 = 144 square feet

area of dining room = 10*10 = 100 square feet

so the combined area would be 144+100 = 244 square feet

i believe the answer is d.

hope it you! : d

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
