Create an area model to show 6 x 42 distributed.
The area model should illustrate:
(6 x 40) + (6 x 2)
The perimeter of the rectangle is 134 meters. The rectangle's length is 42 meters. What is the width of the rectangle?
Width = 25 m
P = (2L) + (2W)
134 = (2x42) + (2W)
134 = 84 + (2W)
134 = 84 + 50
50/2 = 25
The area of the rectangle is 435 square meters, and the length is 3 meters. What is the width of the rectangle?
A = L x W
435 = 3 x W
W = 145 meters
Mr. Gerry has 42 widgets to store in containers. Each container can hold 5 widgets. How many boxes will be full with widgets?
8 boxes will be full of widgets.
There will be 2 widgets leftover. The remainder is ignored based on the story and question.
The following students flew paper airplanes and measured the distance flown in meters.

What is the difference in length between the shortest and longest travel distances? Show your work.
4 3/5 - 3 2/5 = 1 1/5 meters
The difference in lengths is 1 1/5 meters.
Use the doubling & halving strategy to find the missing value.
24 x 64 = ? x 32
? = 48
24 x 64 = 48 x 32
64 was halved so 24 had to be doubled (24 x 2)
The perimeter of the rectangle is 376 centimeters. The width is 76 centimeters. What is the length of the rectangle?
Width = 112 cm
P= (2L) + (2W)
376 = (2L) + (2x76)
376 = (2L) + 152
376 = 224 + 152
376 = (112 x 2) + 224
The rectangle has a width of 14 meters and a length of 22 meters. What is the area of the rectangle?

Zac came along and said he could throw a paper airplane the combined distance of the top three already thrown. How far does Zac think he could throw his paper airplane?
4 1/5 + 4 1/5 + 4 1/5= 12 3/5
Zac thinks he can throw his paper airplane 12 3/5 meters.
Which statement is true?
A) 13 x 46 = 14 x 56
B) 36 x 18 = (30 x 8) + (6 x 10)
C) 26 x 7 = (25 x 7) + (1 x 7)
D) 59 x 12 = (60 x 12) + (1 x 12)
C) 26 x 7 = (25 x 7) + (1 x 7)
26 x 7 = 182
25 x 7 = 175
1 x 7 = 7
175 + 7 = 182
The rectangle's area is 96 square centimeters. The width is 12 centimeters. What is the perimeter of the rectangle?
A = L x W
96 = L x 12
L = 8
P = (2L) + (2W)
P = (2x8) + (2x12)
P = 16 + 24
P = 40 centimeter
The area of a rectangle is 6,012 square centimeters. The width is 6 centimeters. What is the length of the rectangle?
