<span>1)
3 3/8= </span>(3/1) + (3/8)=
= (3x8)/8 + (3/8)
=(3x8 +3) / 8 putting both numbers with the same denominator
=27/8
27 is the same as 3³ 3x3x3= 27
8 is the same as 2³ 2x2x2= 8
= 3³÷ 2³
2)
1 11/25= (1/1) + (11/25)
= (25/25) + (11/25) putting both numbers with the same denominator
= (25+11)/25
=36/25
36 is the same as 6² 6x6=36
25 is the same as 5² 5x5=25
6²/5²

Width = 10 feet
Length = 40 feet
================================================
Explanation:
W = width
L = 4W = four times the width = length
P = perimeter
P = 2*(W+L)
P = 2*(W+4W)
P = 2(5W)
P = 10W
The perimeter is 100 feet.
P = 100
10W = 100 .... plug in P = 10W
W = 100/10 .... divide both sides by 10
W = 10
The width is 10 feet.
L = 4W
L = 4*10
L = 40
The length is 40 feet.
-----------------
Check:
P = 2(L+W)
P = 2(40+10)
P = 2(50)
P = 100
or another way to check is to add up the four sides {10, 40, 10, 40}
10+40+10+40 = 50+50 = 100
This confirms the answer.
