The phrase "stared us in the face" is an idiomatic expression.

It means that something was very obvious or impossible to ignore.

Explanation

5 masons can build a house in 120 days.

This means the total work required to build the house is:

5 masons × 120 days = 600 mason-days

To build the same house in 75 days, the total work required remains the same (600 mason-days).

Let's divide the total work by the new timeframe:

600 mason-days ÷ 75 days = 8 masons

Explanation

The area of a rectangle is length × width:

Area = length × width

16 = 8 × width

Divide both sides by 8:

width = 2

The perimeter of a rectangle is 2 × (length + width):

Perimeter = 2 × (8 + 2)

= 2 × 10

= 20
