Question

Find the area of a triangle whose sides are 35 cm, 45 cm and 50 cm.​

Answer 1

Answer:

s=a + b + c

2

=  

35 + 45 + 50

2

=  65 centimeters

Area =  √s(s-a)(s-b)(s-c)

=  √65×(65 - 35)×(65 - 45)×(65 - 50)

=  764.85292703892 centimeters2

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
