57 is the same as g and 231.
We could also say that 57 is equal to g and 231.
57= g + 231
I hope this helps!

(b•h)1/2
(4•5)1/2
(20)1/2
10 is the answer
The correct question is
<span>Brett made a scale drawing of a rectangular room in his house. The actual length of the room is 12 4/5 ft. The scale used to make the drawing was 1/4 in.=1 ft. What is the length, in inches, of the room on the drawing?</span>
we know that
scale=measure in the drawing/measure in the actual
measure in the drawing=measure in the actual*scale
in this problem
scale=1/4 in/ 1 ft-----> 1/4
measure in the actual=12 4/5 ft-----> (12*5+4)/5----> 64/5 ft
so
measure in the drawing=(64/5)*(1/4)----> 3.2 in
the answer is
the length, in inches, of the room on the drawing is 3.2
I'm pretty sure the answer would be 30 people.
