Answer 1

Answer:

18.50 ft

Step-by-step explanation:

Add 1.25 to the length:

3 + 1.25 = 4.25

The formula for the perimeter of a rectangle is: L + L + W + W.

To find the perimeter quicker, multiply the length and width by 2, then add.

5.00(2) = 10.00

4.25(2)= 8.50

10.00 + 8.50 = 18.50

Answer 2

Answer:

• 21.

Step-by-step explanation:

The Length and width is 1.25 longer than the first one.

• 3 + 1.25 = 4.25.

• 5 + 1.25 = 6.25.

2 ways:

• 4.25 + 6.25 + 4.25 + 6.25
• (4.25 + 6.25)*2

Solve first way:

• 4.25 + 6.25 + 4.25 + 6.25
• = (4.25 * 2) + (6.25 * 2)
• = 8.5 + 12.5
• = 21.

Solve second way:

• (4.25 + 6.25)*2
• = 10.5 * 2
• = 21.

Your answer is 21 ft.
