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
84 is divisible by 2, 3, 4, 6
answer is 2827.43338823081 . 20^2 + 15^2
400+225
square root of 625
is 2827.4
