Question

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

Answer 1

Step-by-step explanation:

Dimensions:

a = 35cm

b = 45cm

c = 50cm

Semiperimeter(s) = a+b+c/2

= 35 +45 +50 /2

= 65 cm

Area = root [s(s-a)(s-b)(s-c)]

= root [65(65-35)(65-45)(65-50)]

= root [65 × 30 × 20 × 15]

= root [585000]

= 764.85 sq.cm (approx)

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
