Question

Find the perimeter of a triangle is 543 CM the sides 186 CM and 144 CM find the third sides.

Answer 1

Answer:

Let the value of 3rd side be:

y

Perimeter = sum of all sides

⇒ 186 + 144 + y = 543

330 + y = 543

y = 543 - 330

y = 213

VERIFY:

186 + 144 + y = 543

186 + 144 + 213 = 543

330 + 213 = 543

543 = 543

Hence, verified
