Question

Draw three examples of rectangles that have the same perimeter,but different areas.note which of the areas is greatest and which is the least.

Answer 1

1.) P=2L+2W L=14 W=1- 14 + 14 + 1 + 1 = 30 P=30-----A=LW 1 times 14 = 14 A=14

2.) P=2L+2W L=11 W=4 11 + 11 + 4 + 4 = 30 P=30-----A=LW 4 times 11 = 44 A=44

3.) P=2L+2W L=7 W=8 7 + 8 + 7 + 8 = 30 P=30----A=LW 7 times 8 = 56 A=56


****L = length
W= width
A= area
A=LW----area = length times width
P=2L+2W-----perimeter = two lengths plus two widths
