The area and perimeter of a triangle is 41.85 square cm and 30.3cm respectively.
How to find the area and perimeter of triangle?
Triangle is a 2-dimensional shape with 3 sides and angles.
Area of triangle = 0.5 * base * height
Given the following
base = 9cm
Height = 9.3cm
Find the area
Area = 0.5 * 9 *9.3
Area = 41.85 square cm
Find the perimeter
The perimeter is the sum of all its sides
Perimeter = s1 + s2 + s3
Perimeter = 9cm + 12cm + 9.3cm
Perimeter = 30.3cm
Hence the area and perimeter of a triangle is 41.85 square cm and 30.3cm respectively.
