Q1

The perimeter of a triangular garden is 900 cm and its sides are in the ratio 3.5.4. Find the area of triangular garden​

Answer 1

Answer:

First we need to find the sides..

BTP,

3x+5x+4x= 900

12x =900

X= 900/12

75

3x= 3*75=225

5x = 5*75=375

4x = 4*75=300

then area=

a+b+c/2= 225+375+300/2

=900/2= 750

then we need to find

✓750(750-225)(750-375)(750-300)

You will get your answer.. I hope it will help you.. Thanks

Answer 2

Answer:

let the side of triangular garden are 3x,5x,4x.

perimeter =addition of sides

900= 3x+5x+4x

900=12x

x=75cm

sides are 225,300,375

area=√s(s-a)(s-b)(s-c)

were a,b,c are side and s is semi perimeter that is 450cm

by Putting value we get

√450(450-225)(450-300)(450-375)

√450×225×150×75

√225×2×225×150×75

√225×225×150×150

225×150

33750 cm²
