Question

find the area of triangle whose perimeter is 168cm and two of its sides are56cm and 60 cm

Answer 1

The area of triangle is  1344 sq.cm.

Step-by-step explanation:

Sides of triangle are 56 cm and 60 cm

Let the third side be x

Perimeter of triangle = Sum of all sides = 56+60+x

We are given that perimeter is 168 cm

56+60+x = 168

116+x=168

x=168-116

x=52

So, a= 56 cm

b = 60 cm

c = 52 cm

Area of triangle =$\sqrt{s(s-a)(s-b)(s-c)}$

Where$s = \frac{a+b+c}{2}$

$s = \frac{56+60+52}{2}$

s =84

Area of triangle =$\sqrt{84(84-56)(84-60)(84-52)}$

Area of triangle =$1344 cm^2$

Hence The area of triangle is  1344 sq.cm.
