Answer 1

#1

Rectangle area:

• A = lw

Given:

• l = 12 ft, A = 300 ft²

Find w:

• 12w = 300
• w = 300/12
• w = 25 ft

#2

Perimeter is the sum of side lengths:

P = 2 1/4 + 5 2/5 + 5 17/20 =

2 + 5 + 5 + 1/4 + 2/5 + 17/20 =

12 + 5/20 + 8/20 + 17/20 =

12 + 30/20 =

12 + 1.5 =

13.5 ft

• Cost of a shirt = $19.99
• Number of shirts = 6

Total cost:

• $19.99*6 = $119.94
