Question

Find the perimeter and area of the triangle whose sides are of length 56cm 52 cm and 60cm respectively

Answer 1

here is your answer bro.

Answer 2

Given :-

↪We have given the sides of triangle are 56cm , 52cm and 60cm

To Find :-

Find the Perimeter and Area of Triangle

SoLution :-

We know that, the formula to find the perimeter of Triangle is :-

$\implies$ Sum of all Sides

$\implies$ 56 + 52 + 60

$\large{\boxed{\bf{perimeter=<strong> </strong>168 \:cm}}}$

Now, we find the area of triangle by heron's Formula

firstly, we have to find the semi perimeter of sides

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

s =$\frac{168}{2} = 84$

We know that, the formula to find the area of triangle is :-

$\sqrt{s(s - a )(s - b)(s - c)}$

putting the values in formula

$\sqrt{84(84 - 56)(84 - 52)(84 - 60)}$

$\implies$$\sqrt{84 \times 28 \times 32 \times 24}$

$\implies$$\sqrt{1806336 }$

$\implies$ 1344 cm²

Hence, the area of triangle is 1344 cm²
