Answer: 50cm x 50cm
312 is the LCM for this set
to find the hypotenuse length you need to use the pythegorian therum and that will give you 29cm
The best answer to go with is b
Million has 6 zeoes
34,000,000+256,00*400
PEMDAS
multiply first
256,000*400=102,400,000
add to 34,000,000
136,400,000
now
must be in form
(x)(10^m)
such taht
1<x<10
and x times 10^m is the original number
1.364*10^8
