I already answered this question.
Answer and Step-by-step explanation:
In this inequality, we are solving for r. Just think of this as a normal equation, and worry about the sign at the end.
First, add 5 to both sides.
8r > 80
Now divide by 8 to both sides.
r > 10
So, r is greater than 10.
[ If the inequality had a negative number being divided, then the sign would flip.
For example:
-2x > 4
To solve this one, you would divide by -2 to both sides. Then, you would flip the sign.
x < 2 ]

We know that
in the right triangle ACD
Applying the Pythagoras theorem
AC²=AD²+CD²------> AD²=AC²-CD²-----> AD²=5²-4²---> AD²=9----> AD=3
let
∅=angle CAD
tan ∅=4/3
in the right triangle CDB
the angle DCB is equal to ∅
tan ∅=DB/CD-------> DB=CD*tan ∅------> DB=4*(4/3)----> DB=16/3
AB=AD+DB-----> 3+16/3----> AB=25/3----> AB=8.33
the answer is

Answer:
Step-by-step explanation:
let width=x
length=3x
area=3x×x=3x²
3x²=192
x²=192/3=64
x=√64=8
width=8 m
length=3×8=24 m
