112/2=56 (sum of both lengths)
4x=56
x=14
length=42
width=14
100 square centimeters means the dimensions are 10x10
but the actual floor will be 1cm:2ft
so 10cm=20feet
making the dimensions 20feetx20feet
the area of the actual floor is 400 feet
Answer:87.63

2x +3=7
-3 -3
2x=4
divide both sides by 2
x=2
the answer is 2
