Question

find area of trianglewhose two sides are 195m and 180m and perumeter is 450m

Answer 1

HI FRIEND.!!!!!!

HERE IS UR ANSWER.......

The perimeter of triangle is 450m
sum of all sides = 450
let other side be x
x+180+195 = 450
x = 450 - 375
x = 75

S = a+b+c/2
= 450/2
= 225

area of triangle = √s(s-a)(s-b)(s-c)

= √225(225-195)(225-180)(225-75)

= √225(30)(45)(150)

= √225(10×3)(15×3)(15×10)

= √15²10²15²3²

= 15×10×15×3

= 225×30

= 6,750m²

Answer 2

Hello Dear!!!

Here's your answer....

Given that,

Sides of the triangle are 195 and 180.

Let,

the third side be 'x'

Perimeter = sum of three sides..

450 = 195+180+x

450 = 375+x

450-375 = x

75 = x

Third side is 75.

According to heron's formula,

Let, s be semi perimeter... a,b,c are sides..no hmm

semi perimeter is 1/2 of perimeter

semi perimeter = 450/2
= 225

Area = √s*(s-a)*(s-b)*(s-c)

Area = √225*(225-195)*(225-180)*(225-75)

Area = √225*30*45*150

Area = √45562500

Area = 6750.

Area of the triangle is 6750.
