Find the perimeter of an equilateral triangle. The length of two sides of the triangle (a) is 30 cm, and the base is 8 cm.

Step: 1

Given, length = 30 cm base = 8 cm

Explanation:

The length is 30 cm and the base measures 8 cm.

Step: 2

Perimeter of equilateral triangle (P)= 2a + b

Explanation:

The formula for finding the perimeter of an equilateral triangle is P = 2a + b.

Step: 3

Therefore, the perimeter of the equilateral triangle is 68 cm.

Explanation:

To find the value of P, we substitute 30 for the variable and solve the equation 2(30) + 8, which results in P being equal to 68 cm.
