Question

The lengths of the sides of a triangle can be represented by these three expressions:`(7/8 x + 3/4y), (2y-1) and (y - 1/2x + 2/3)`. What is the perimeter of the triangle?

Answer 1

`=(3/8)x + 3(3/4)y - (1/3)`

Explanation:

Perimeter of a triangle = sum of the three sides.

Perimeter `= (7/8)x + (3/4)y + 2y -1 + y -(1/2)x + (2/3)`

Combining like terms together,
=`(7/8)x -(1/2)x + (3/4)y + 2y + y -1 + (2/3)`

`= (3/8)x + 3(3/4)y -(1/3)`
