Answer 1

2 1/4 inches

Explanation:

We are to line up all of the 3/4 inch buttons.

There are 3 of these buttons; this gives us a length of

3/4(3) = 3/4(3/1) = (3*3)/(4*1) = 9/4 = 2 1/4 inches

Answer 2

.25*3=.75
.375*2=.75
.5*2=2.0
.625*2=1.25
.75*3=2.25
.875*2=1.75
1*2=2
1.25*2=2.5
1.5*2=3
1.5+2=3.5
1.25+2.25=3.5+3.5=7
3.5+1.75=5.25
5.25+4.5=9.75
9.75+3=12.75

answer = 12.75in^2
