Answer:
Area of polygon = 16.11 square cm
Step-by-step explanation:
From the figure we can divide the polygon into two quadrilateral,
1) a square with side 3.6 cm
2) a rectangle with dimensions 2.1 x 1.5
<u>To find the area of square</u>
Area = side x side = 3.6 x 3.6
= 12 .96 square cm
<u>To find the area of rectangle</u>
Area = Length x Breadth
= 2.1 x 1.5 = 3.15 square cm
<u>Area of polygon</u>
Area = 12.96 + 3.15 = 16.11 square cm
LW=105
L+W=26
L=26-W
(26-W)W=105
26W-W^2=105
0=W^2-26W+105
-105=W^2-26W
-105+169=W^2-26W+169
64= (W-13)^2
8= -(W-13) and (W-13)
8= -W+13
5=W
8= W-13
21=W
105= 5*21

Answer:
Alice's weight is 100 lbs.
Step-by-step explanation:
Let's denote Jane's weight by J, and Alice's weight by A.
The exercise says that Jane is 20 lbs heavier than Alice. So that if you add 20 lbs to Alice's weight, you get Jane's weight. In equation form:
It also mentions that Jane's weight is 120% that of Alice. So that if you multiply Alice's weight by 1.2, you get Jane's weight. In equation form:
Plugging this second equation onto the first equation, we get:
And now solving for A:
Therefore Alice's weight is 100 lbs.
