Answer:

Step-by-step explanation:
<u>Formula for area of rectangle:</u>
= length × width
<u>Area of the smaller rectangle:</u>
length = 7
width = 6
= 7 × 6
= 42
<u>Area of the larger rectangle:</u>
length = 7 + 4 = 11
width = 6 + 2 = 8
= 11 × 8
= 88
<u>Area of the shaded region:</u>
= Area of the larger rectangle - Area of the smaller rectangle
= 88 - 42
= 46

To find the ratio, you Will need to find the ratio of the patio, and the ratio of the scale version of the patio.
16 feet x 20 feet = 320 ft.²
(16/4 = 4 in)/(20/4= 5 in)
4 inches x 5 inches = 20 in.²
320 ft.² / 20 in.² = 16 ft.² / 1 square inch
