Question

1. find the perimeter and area of this triangle. dimensions are in centimeters.

triangle with two equal sides of 14 cm, base 18 cm, and height 8 cm

Explanation:

Step1: Calculate the perimeter

The perimeter of a triangle is the sum of all its sides. The sides are 14 cm, 14 cm, and 18 cm.
$Perimeter = 14 + 14 + 18$
$Perimeter = 46$ cm

Step2: Calculate the area

The area of a triangle is given by the formula $Area = \frac{1}{2} \times base \times height$. Here, the base is 18 cm and the height is 8 cm.
$Area = \frac{1}{2} \times 18 \times 8$
$Area = 9 \times 8$
$Area = 72$ $cm^2$

Answer:

Perimeter: 46 cm, Area: 72 $cm^2$
