Area = length * width
241.2 = 15 * width
Width = 241.2/15 = 16.08 meters
Perimeter = 2*length + 2*width = 62.16 meters
I believe it is 8x.
Use the formula A=1/2(b*h)
A=1/2(4x(5x-1))
A=1/2(20x-4x)
A=1/2(16x)
A=8x
Answer:
9 days.
hope it helps
Step-by-step explanation:
As per given data
1/x=1/(x+27)+1/(x+3)
1/x=(x+3+x+27)/(x+27)(x+3)
X^2+30x+81=2x^2+30x
X^2=81
X=9
so A&B can together do the work in 9 days
