Expanding the digits, we have

Answer:
Length = 45 inches and Width = 20 inches
Step-by-step explanation:
Let the width be w.
Length(l)=2.25w
Area = 900 in^2
The formula for the area of a rectangle is Area = length * width
So substituting our values we get:

So we get width = 20 inches
Length = 2.25w
so Length= 2.25*20
=45 inches
A number squared would be x squared (x^2)
The product of x squared and ten is 10x^2
Then subtract nine
10x^2 - 9
Answer:
<h2>1005.12</h2>
Step-by-step explanation:
<u>first</u><u> </u><u>we </u><u>need</u><u> to</u><u> </u><u>know</u><u> that</u><u> </u><u>r</u><u>edious</u><u> </u><u>isn't</u><u> </u><u>gien</u>
so we have to find redious
according to Pythagoras theorem
a²+b²=c²
a=√c²-b²
a=17²-15²
a=√(17+15)(17-15)
a=√64
a=8
