Question

Answer 1

Step-by-step explanation:

1. area of triangle = 1/2 × Base × height
2. perimeter of triangle = sum of all three sides

Answer 2

Answer:

heya....!!!!

Since all the three sides of the triangle are of equal length, we can find the perimeter by multiplying the length of each side by 3. 20 + 20 + 20 = 3 × 20 = 60 cm. Thus, the perimeter of an equilateral triangle is 3 times the length of each side. Area of a two-dimensional shape is the space occupied by the shape.
