Answer:
Width = 12
Length = 58
Step-by-step explanation:
Width = x
Length = 4x + 10
Perimeter = 140
2 * ( length + width ) = 140
2 * (4x +10 + x) = 140
5x + 10 = 140/2 = 70
5x = 70- 10
5x = 60
x = 60/5 = 12
Width = 12
Length = 4 * 12 + 10 = 48 +10 = 58
A = 2bs + b^2; where A = area of pyramid; b = base length; s = the slant height;
136 = 8s + 16 ;
8s = 120;
s = 15 inches;
3/5 = 51/85
Therefore, 51 red marbles and 85 green marbles follows the required ratio.
