Question

)The sides of a triangle are(3y + 1), (4y + 2) and (7y). Find the

perimeter of the triangle.
a) 14y + 3
b) 15y +3
c) 8y + 2
d) 7y + 3

Answer 1

a

Explanation:

The perimeter is the sum of the 3 sides of the triangle, that is

perimeter = 3y + 1 + 4y + 2 + 7y ← collect like terms

= 14y + 3

Answer 2

perimeter of the triangle = addition of all sides.

perimeter = 3y + 1 + 4y + 2 + 7y

perimeter =3y + 4y +7y +1 + 2

perimeter = 14y + 3

answer = option a.
