Question

A triangle shaped land has the sides into the retio 3:5:7 if its peri meters is 300 meter what will be the area of land ?​

Answer 1

perimeter of a triangle= sum of all sides

3x+5x+7x = 300

15x = 300

x = 20

60 , 100 , 140 are the side of a triangle

area of a triangle

s= 60+100+140/2

s= 150

whole under root s (s_a) (s_b) ( s_ c)

whole under root 150( 150 _60) ( 150_100)(150_140)

whole under root 150×90×50×10

under root 6750000

answer is 2598.07
