Q4 Find the area of a triangle wiose des e tespectively 150 cm 120 and 200m
​

Answer 1

Hello mate..

Solution:

Given: The three sides are:

• a = 150cm
• b = 120cm
• c = 200cm

To Find:

Area of the triangle with the given sides.

We Know That,

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

Here, s = semi - perimeter of the triangle.

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

s = $\bold{\frac{150+120+200}{2} }$

s = $\bold{\frac{470}{2}}$

s = 235.

Then,

$\bold{=\sqrt{235(235-150)(235-120)(235-200)} }$

$\bold{\implies \sqrt{235(85)(115)(35)} }\\ \bold{\implies \sqrt{80399375} }\\ \bold{\implies 8966.5}$

Therefore, area of the triangle is 8966.5 cm².

HOPE THIS HELPS YOU..
