Question

can you guys please help me with this I am not getting it .​

Answer 1

let the ratios of sides be 2x, 3x and 4x

perimeter of triangular garden is 108

hence, 2x+3x+4x = 108

9x = 108

x= 108/9

hence, x = 12

hence,

2x=2×12=24m

3x=3×12=36m

4x=4×12=48m

S = 24+36+48/2

= 108/2

= 54

hence, semi perimeter = 54

Area= √90(90-24)(90-36)(90-48)

= √90×66×54×42

= √13471920

=3670.411sq.m

Hence,the area of the triangular garden is 3670.411sq.m

Hope this will help you !
