Answer:
Length = 30
Width = 5
Step-by-step explanation:
So the formula for perimeter is
P = 2L+2W
And we know that:
L = 6W
So then we put in all the information that we do know
70 = 2(6W)+2W
And pop that into a calculator and you get W=5
So now we put that information into L = 6W to get:
L = 6×5
L = 30

10/100=x/30
Cross multiply
100x=300
Divide each side by 100
X=3
907.46ft²÷3.14=289
√289=√r²
17=r
Answer:
x = 22/3
Step-by-step explanation:
QR + RS = QS
=> 2x + 1 + 4x + 17 = 9x - 4
-3x = -22
x = 22/3
