Question

Find side of equilateral triangle whose perimeter is 45m

Answer 1

Answer:

LET THE LENGTH OF THE SIDE OF THE TRIANGLE BE X

AS THE TRIANGLE IS EQUILATERAL THE SIDES ARE EQUAL .SO,

X+X+X = 45

3X = 45

X =45/3

X = 15

THEREFORE THE LENGTH OF THE SIDE IS 15m

Answer 2

Answer:

The side of an equilateral triangle is 15 m .

Step-by-step explanation:

Given information,

Perimeter of equilateral triangle is 45 m.

We have to find out the side of an equilateral triangle.

Equilateral triangle means the triangle which is having all equal sides.

By finding the length of one side we can find out the length all sides.

As we know that,

The perimeter of equilateral triangle = 3S

Where,

S is the side of an equilateral triangle.

By putting given values in the formula

45 = 3S

$S = \frac{45}{3}$

S = 15

Hence,

The side of an equilateral triangle is 15 m .
