Answer:
Step-by-step explanation:
let x and y be the sides of the rectangle.
2(x+y)=44
x+y=44/2=22
y=22-x
1 tile=1 sq. ft.
120 tiles=120 sq.ft.
area=120 sq.ft.
xy=120
x(22-x)=120
22x-x²=120
x²-22x+120=0
x²-12x-10x+120=0
x(x-12)-10(x-12)=0
(x-12)(x-10)=0
x=12,10
if x=12
y=22-12=10
if x=10
y=22-10=12
floor dimensions are 12 ft ×10 ft
Step-by-step explanation:
Formula for compound interest is given by

Where
A is the amount at the end of the period
P is the principal
R is the rate
n is the period
The interest = A - P
From the question
P = $ 3200
n = 3 years
R = 40%
So we have

A = $ 8780.80
<h3>The amount is
$ 8780.80</h3>
The interest is
$ 8780.80 - $3200
<h3>= $ 5580.80</h3>
Hope this helps you
