Answer is:
15N and 5N
Explanation:
Two like parallel forces are acting at a distance of 24mm apart and their resultant is 20N. If the lines of action of the resultant is 6mm from any given force, the two forces are 15N and 5N.

Answer is:
twice the area of the triangle
Explanation:
Three forces acting on a rigid body are represented in magnitude, direction and line of action by the three sides of a triangle taken in order. The forces are equivalent to a couple whose moment is equal to twice the area of the triangle.
