Sam purchased 625square feet of carpet for his bedroom which is shaped as a square. what are the dimensions of his bedroom? each side of the bedroom has a length of
a. 25ft
b. 156.25ft
c. 390,625ft
d. 312.5ft
i think b

It's A!
square feet means you have to find it's square root!
Remember his bedroom is a square, so each side has equal length.
the square root of 625 is 25
We can check!
area=length*width
since the length and width is the same plug in 25 for both
area=25*25
area=625

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
