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
Answer:
I'm confused by this. What do they mean by prove?
Step-by-step explanation:
Answer:
The answer to your question is: V = 5x² + 40x + 80
Step-by-step explanation:
Formula = V = r²h
r = x + 4
h = 5
Substitution
V = (x + 4 )² 5
V = (x² + 8x + 16)5 expand
V= 5x² + 40x + 80 simplify
The mark up percentage of each order is 400%
<h3>How to determine the percentage mark up?</h3>
The given parameters are:
Cost price = $4
Selling price = $20
The mark up percentage is calculated as:
Mark up percentage = (Selling price - Cost price)/Cost price * 100%
Substitute the known values in the above equation
Mark up percentage = ($20 - $4)/$4 * 100%
Evaluate the difference
Mark up percentage = $16/$4 * 100%
Evaluate the quotient
Mark up percentage = 4 * 100%
This gives
Mark up percentage = 400%
Hence, the mark up percentage of each order is 400%
