HELP ME PLEASE THIS IS DUE TMRW 9. A large square room has an area of 144 m².
a) Find the length of a side of the room.
b) How much baseboard is needed to
go around the room?
c) Each piece of baseboard is 2.5 m long.
How many pieces of baseboard
are needed?

Step-by-step explanation:

a.144m2. take the square root of that to find the length of one side of the room

the square root would be 12m

b. this is basically asking for the perimeter. since you have one side of the room, you can find the perimeter now by multiplying one side by 4, because a square has 4 equal sides. 12 times 4 is 48m

c. each piece of the baseboard is 2.5m, you need 48 m of baseboard. divide  48/2.5 to get your answer. 19.2 pieces of baseboard, or 20 if you want to get technical

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
