Answer:
r = -8/5
Step-by-step explanation:
-7 log4 (-10r) = -14
Divide each side by -7
-7/-7 log4 (-10r) = -14/-7
log4 (-10r) = 2
Raise each side to the base of 4
4^ log4 (-10r) = 4^2
-10r = 16
Divide each side by -10
-10r/-10 = 16/-10
r = -116/10
r = -8/5
In this question, there are two garden with same area but different shape (rectangle and square). The formula for rectangle area is length* width, so the area of the garden would be:
rectangle garden area= 4m * 16m= 64m^2
The formula for the square area would be side^2. The square garden area is same as the rectangle garden area. Combining both equations will result in:
square garden area= rectangle garden area
side^2= 64m^2
side= √64m^2= 8m
A=π(4)2=π·42≈<em>16pi ft^2</em>
