Algebraic expression

Question

A four sided field needs to be fenced. Two sides are each g feet long. The length of the third side is 3ft less than 5times the fourth side. If the length of the fourth side is represented by m , write an algebraic expression that represents the length of the fencing needed.

Answer 1

2 sides = g + g = 2g

3rd side = 5m-3

4th side = m

Perimter = total fencing required

sum of 4 sides = 2g+5m-3+m

= 2g +6m -3
