Brennan makes a scale drawing of a fort. The scale for the actual fort to the scale
hoa [83]

Answer:

The dimensions of the fort in the drawing is 7 in by 5.5 in

Step-by-step explanation:

A scale can be used to either increase or decrease the size of a given object.

From the question, Brennan used a scale of 3 feet to 1 inch.

scale = \frac{actual fort}{scale drawing}

The dimensions of the fort are 21 ft by 16.5 ft. Thus, to determine the dimensions of the drawing;

\frac{3 ft}{1 in} = \frac{21 ft}{y}

y = \frac{21 ft *1 in}{3 ft}

  = 7 in

Also,

\frac{3 ft}{1 in} = \frac{16.5 ft}{z}

z = \frac{16.5 ft*1 in}{3 ft}

  = 5.5 in

Dimensions = y by z = 7 in by 5.5 in

Therefore, the dimensions of the fort in the drawing is 7 in by 5.5 in.
