Concepts and Skills

Question 3.
Kevin has a rectangular rug that has a perimeter of 16 feet. Draw a rectangle that could represent Kevin’s rug.  Explanation:
perimeter is 16 feet.
p = 2 (l + w)
16 = 2 (l + w)
l + w = 8
let us consider l = 3
and w = 5
3 + 5 = 8

Question 4.
Use Tools Pablo draws a rectangle that has a length of 3 feet and a width of 4 feet. Select all the rectangles that have the same area and a different perimeter. Tell what strategy and tool you will use to solve the problems, explain your choice, and then find the answers.
(A) length 6 feet, width 2 feet
(B) length 3 feet, width 3 feet
(C) length 7 feet, width 1 foot
(D) length 1 foot, width 12 feet
(E) length 2 feet, width 5 feet
Explanation:
length 6 feet, width 2 feet
area = l x w
= 6 x 2 = 12
p = 2 (l + w)
p = 2 x 8
= 16
length 1 foot, width 12 feet
area = l x w
= 1 x 12
= 12
p = 2 (l + w)
p = 2 x 13
p = 26
I have used the formula for finding the area and perimeter.
