Mathematics: Ari is designing a patio that will be 20 feet long and 16 feet wide. he makes a scale drawing of the patio using a scale of 1 inch to 4 feet. the ratio of the area of the scaled drawing to the actual area of the patio is 1 square inch to square feet.

The inverse function y = - 12 is (x) = Step-by-step explanation:...

1 square inch to 16 square feet

Step-by-step explanation:

The real patio area is

$20\cdot 16=320\ ft^2$

The dimensions of the scale drawing are

$20:4=5\ in\text{ and }16:4=4\ in,$

so the area of the scale patio is

$5\cdot 4=20\ in^2$

The ratio of the area of the scaled drawing to the actual area of the patio is

20:320=1:16

or 1 square inch to 16 square feet.
