Question

perimeter the perimeter of stephanies triangle is half the perimeter of juans triangle. juans triangle is shown. write a numerical expression to describe the perimeter of stephanies triangle. 5 ft 12 ft 8 ft o 5 + 8 + 12 o 5 8 12 o 5 * 8 - 12 o 5 + 8 + 12 / 2

Explanation:

Step1: Recall perimeter formula

The perimeter of a triangle is the sum of the lengths of its sides. For Juan's triangle with side - lengths 5 ft, 8 ft, and 12 ft, the perimeter of Juan's triangle is \(5 + 8+12\).

Step2: Find Stephanie's triangle perimeter

Since Stephanie's triangle perimeter is half of Juan's triangle perimeter, the expression for Stephanie's triangle perimeter is \((5 + 8 + 12)/2\).

Answer:

\((5 + 8 + 12)/2\)
