Question

By using HERON'S FORMULA
Find the area of a triangle whose sides are 35 cm 45 cm and 50 cm. ​

Answer 1

Answer:

A≈764.85cm²

a Side

35

cm

b Base

45

cm

c Side

50

cm

Answer 2

Given :-

Sides of triangle = 35 cm, 45 cm and 50 cm

To Find :-

Area of triangle

Solution :-

We know that

• Semi-perimeter = a + b + c/2

• Semi-perimeter = 35 + 45 + 50/2
• Semi-perimeter = 130/2
• Semi-perimeter = 65 cm

Now, finding area

• Area = √s(s - a)(s - b)(s - c)
• Area = √65(65 - 35)(65 - 45)(65 - 50)
• Area = √65 × 30 × 20 × 15
• Area = √585000
• Area = 764.85 cm²
