<span>This polygon is composed of a right triangle and <span>a parallelogram.
The area of right angle :
The area of the </span></span><span>parallelogram</span>:
The area of the polygon is equal:
Therefore, the answer is:
Width = x
length = x+10
Area of deck = 144 square feet
Area = length * width
144 = x(x+10)
Solving for x in a quadratic:
x²+10x = 144
x²+10x-144 = 0
Factor:
(x+18)(x-8) = 0
Solving for x:
x = 8, x = -18
Dimensions cannot be negative, therefore x = 8, only.
Length = x + 10
Length = 18
Width = 8

Answer: 9.44 cm
Step-by-step explanation:
A = b × h
A = 4 × 2.36
A = 9.44 cm
To find the area of a parallelogram, the formula to use is A = b × h.
Interest rate = 5.25%
<u>Step-by-step explanation:</u>
Simple Interest = Pnr = 4252.50
n = time = 54 months = 4.5 years
r = rate of interest = ?
P = 18,000
r = SI/Pn = 4252.50 / 18000× 4.5
= 0.0525 = 5.25%
