Question 928486: Find the ratio of length to area of a rectangle if the ratio of length to perimeter is 1:6 and the area of rectangle is 5000 sq.m ? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! p = 2L + 2w
L/p = 1/6
L/(2L + 2w) = 1/6
Lw = 5000
---
L/(2L + 2w) = 1/6
6L = 2L + 2w
4L = 2w
w = 2L
---
Lw = 5000
L(2L) = 5000
LL = 2500
L = sqrt( 2500 )
L = 50
---
w = 2L
w = 2*50
w = 100
---
answer:
ratio of length to area:
L/LW = 1/W = 1/100 = 0.01
