cestrela7 [59]

Answer:

1 inch equals 8 feet

Step-by-step explanation:

Given that;

Abigail drew a scale drawing of the oldest house in her town.

The actual  length of the house = 64 feet long

Abigail scale drawing =  8 inches long

The scale he used in drawing the house is determined by choosing a perfect scale:

i.e

If 8 inches is used to draw an actual length of a house which is 64 feet long,

Then 1 inch should be able to draw (64 feet * 1 inch)/ 8 inches

So, 1 inch should be able to draw 8 feet long
