A blueprint scale is 1/4 inches = 1ft.

If the blueprint measurement is 3 in x 3 in, what should you cut?

If 1/4 inches ---> 1 ft

then 1 inch -----> 4 ft
and 3 inches ---> 12 ft

To determine what you should cut based on a blueprint measurement, you need to understand the scale ratio given. In this case, the blueprint scale is 1/4 inches = 1 ft. This means that every 1/4 inch on the blueprint represents 1 foot in real life.

Given that the blueprint measurement is 3 in x 3 in, we can convert this to real-life dimensions using the scale ratio. Since each 1/4 inch on the blueprint represents 1 foot, we can multiply the length and width of the blueprint by this ratio.

For the length:
3 in * (1 ft / 1/4 in) = 3 in * (4 in / 1 ft) = 12 ft

For the width:
3 in * (1 ft / 1/4 in) = 3 in * (4 in / 1 ft) = 12 ft

Therefore, based on the given blueprint measurement of 3 in x 3 in, you would need to cut a piece with dimensions of 12 ft x 12 ft.
