Step-by-step explanation:
L= W+5
P= 9W
P= 2L+ 2W
9W= 2(W+5) + 2W
9W= 2W +10 +2W
9W = 4W +10
5W = 10
W = 2
L=7
P= 9(2)
P= 18
A= LW
A= 7 x 2
A= 14
The length of rectangle is 37.5 and width is 12.5
Step-by-step explanation:
Given,
Width of rectangle = w
Length of rectangle = 3w
Perimeter of rectangle = 100
Perimeter = 2(Length+Width)
![100=2(3w+w)\\100=2(4w)\\100=8w\\8w=100](https://tex.z-dn.net/?f=100%3D2%283w%2Bw%29%5C%5C100%3D2%284w%29%5C%5C100%3D8w%5C%5C8w%3D100)
Dividing both sides by 8
![\frac{8w}{8}=\frac{100}{8}\\w=12.5](https://tex.z-dn.net/?f=%5Cfrac%7B8w%7D%7B8%7D%3D%5Cfrac%7B100%7D%7B8%7D%5C%5Cw%3D12.5)
Width of rectangle = 12.5
Length of rectangle = 3(12.5) = 37.5
The length of rectangle is 37.5 and width is 12.5

5/4 = 1.25
7/4 = 1.75
1.25+1.75=3. They have 3 four leaf clovers.
Raisin = r
blueberry = b
banana = n
r = 18
b = 3r = 18 x 3 = 54
n = b/2 = 54 / 2 = 27
total = 18+54+27 = 99
