Question

Which of the following is the actual length of a wall that is 2 3/4 inches long on a drawing with a scale of 1 inch= 12 feet?

Answer 1

33 feet

Explanation:

Given

1 inch= 12 feet

we have to find actual length of wall when length of wall on drawing is 2 3/4 inches

to do that lets multiply LHS and RHS of above equation with 2 3/4

2 3/4 inches = (2*4 +3 )/4 = 11/4 inches

1 inch* 2 3/4= 12 feet* 2 3/4

1*11/4 inches = 12*11/4 feet = 33 feet

Thus, actual length of wall is 33 feet.
