2) Francine bought a TV that is 31 inches tall and 57 inches wide. She is going to mount it on the wall in her living room. The wall is 8 feet wide and 9 feet tall.

How many square inches of the wall will not be covered by the TV once it is mounted?

Answer 1

Answer:

Hilda needs 64 ft² of tile

8601 in² will be uncovered post mounting

Step-by-step explanation:

Ar=10•6=60 ft²

At=[4•2]/2=8/2=4 ft²

total area=Ar+At=60+4=64ft²

......

Atv=31•57=1767 in²

Aw=(12•8)•(9•12)=10368 in²

Au=Aw-Atv=10368-1767=8601 in²
