Question

The side of triangular park is in the ratio 3:5:7 and the perimeter is 300m. Find its area.

Please answer this question....

Answer 1

Step-by-step explanation:

let 3:4:7 be3x ,5x and 7x

3x + 5x +7x = 300

15 x = 300

x =300/15

x =20

3 x =60

5x = 100

7x =140

area =

a =60 ,b =100 , c =140

s = 60+100+140/2 =150

area =root s ( s-a) ( s-b) (s-c)

= root 150(150-60) (150-100) (150-140)

=root150 ×90 × 50 × 10

= root 15 ×10×9×10×5×10×10

=1500root3
