Question

Write an expression, in terms of h, for the perimeter of this triangle.

Simplify your answer fully.
7
14-6h
3h+3

Answer 1

Perimeter = -3h + 24

Explanation:

Forming the expression,

→ 7 + (14 - 6h) + (3h + 3)

Let's simplify the expression,

→ 7 + (14 - 6h) + (3h + 3)

→ 7 + 14 - 6h + 3h + 3

→ (-6h + 3h) + (7 + 14 + 3)

→ -3h + 24

Hence, answer is -3h + 24.

Answer 2

• P = 24 - 3h

-----------------------------------

It is assumed the sides of the triangle are

• 7, 14 - 6h and 3h + 3

Perimeter is the sum of three sides

• P = a + b + c
• P = 7 + 14 - 6h + 3h + 3 = (7 + 14 + 3) + (3h - 6h) = 24 - 3h
