Question

find length of a side of an equlateral triangle whose petimeter is 3 m nd 12 cm

Answer 1

perimeter=3*s
3m12cm=3*s
312cm=3*s
312/3=s
104=s
Ans=side=104cm or 1.04m

Answer 2

hey!!

here is your answer...

Fact:

✓ equalateral triangle is a type of triangle with each sides equal.

✓ perimeter is the sum of all the sides.

procedure:

1st triangle, perimeter is 3m

let's take lenght as X ,

then, X+X+X = 3

as all the sides are equal and there are three sides in a trinagle.

3X=3

X=1
length of 1st triangle is 1m (or) 100cm

2nd triangle:

lets take lenght as Y

then, Y+Y+Y = 12

3Y=12

Y=4

lenght is the sides in 2nd triangle is 4cm...

this is the first case.. in case if two triangles..




2nd case in case of one angle..

lets convert these measurement into centimeter..

3m and 12 cm

1m =100cm

312 cm

take side as Z

Z+Z+Z = 312.

3Z =312
Z =104..

length is 104 cm

I did it in two cases as the question does not seem ear to me


hope it helps!
