As you see this is a right angle, so the sum of the two angles = 90°
So,
(x + 42) + 3x = 90°
Remove the parentheses:
x + 42 + 3x = 90
Combine like terms:
4x + 42 = 90
Subtract 42 on both sides:
4x = 48
Divide 4 on both sides:
x = 12

2.54 is the legnth
area=2.54 times 2.54=6.4516 cm^2
so a square inch does not equal 2.54 cm^2
