tekilochka [14]
First get the length of the side the was cut (Hypotenuse).

a = 8, b = 3 = 1.5, c = ?

plug into forumla

8^2 + 3^2 = 73

a=8,
b=1.5,
c = sqrt( 73) or 8.5

Now add all sides together to get perimeter...
8+3+8.5 = 19.5

The perimeter of each sheet is 19.5in.

topjm [15]

Answer:

2160 inches

Step-by-step explanation:

The actual length of a soccer field is 300 feet. If the width of the field is 180 feet, then what should the width of the scale drawing be in inches?

1 foot = 12 inches

Width of the field = 180 feet

Hence:

1 foot = 12 inches

180 feet = x

x = 180 × 12 inches

x = 2160 inches

Width of the scale drawing in inches = 2160 inches
