Question

2 sides of a triangle are 48cm and 70cm its perimeter is 1544 find its area

Answer 1

Answer:

=728.27 cm²

Step-by-step explanation:

Given sides of triangle are 48 cm and 70

cm.

Let a = 48 cm

b = 70 cm.

Given perimeter of triangle= 154 cm,

If a, b and c are the sides of the triangle, then the perimeter of the triangle is

given by a + b + c₂

hence 48 +70+ c = 154

⇒c= 36 cm.

Semi perimeter of the triangle is perimeter/2 = 77 cm.

Using Heron's formula, Area of the triangle is given by

A = √s(s-a)(s-b)(s-c)

⇒ A= √77*41*6*28 =728.27 cm²
