For Problems 45-56, set up an algebraic equation and solve each problem. (Objective 3)A blueprint has a scale in which 1 inch represents 5 feet. Find the dimensions of a rectangular room that measures 3 1 2 inches by 5 3 4 inches on the blueprint.

To determine

To Find:

The dimensions of a rectangular room.

Explanation

Approach:

The scale can be convert as follows.

D=kn

Here, dimensions of the shape is D, conversion scale use in blue print scale is k and dimensions measured by scale is n.

Calculation:

The given problems the conversion scale is 1inch = 5feet.

Substitute (5feet1inch) for k and (72inches×234inches) for n in above expression.

D=[(72inches)(5feet
