Answer 1

Answer:

X = 14m = LENGTH OF ONE SIDE

Step-by-step explanation:

we know that sides of an equilateral triangle are equal,,,,,then,,,

perimeter  of equilateral triangle = x+y+ z where {x=y=z}

it also can be written as =x+x+x =3x   .............(1)nation:

the cost of fencing is rupees== 336

the rate of rupees ==8 per metre

then perimeter of the fence = 336/8 = 42m

AS SHOWN ABOVE ,

PERIMETER =42

3X =  42 ...........(1)

X = 42 /3

X = 14 m= LENGTH OF ONE SIDE
