Question

A square and an equilateral triangle have a side in common. If a side of the triangle is 15 mm long .find the perimeter of the figure given along side in centimetre solve

Answer 1

Answer:

Perimeter of figure= 75mm

Step-by-step explanation:

We will only take the side which are outside to the figure

Answer 2

Answer:

7.5cm

Step-by-step explanation:

so, we know that square and Equilateral triiangle have sides which are equal.

Given,

side of triangle: 15mm

Let's Solve

so,1st covert 15mm into cm

1mm: 1/10 cm

So, 1mm will be equal to 1.5cm

Now, perimeter of square: 4*side or a+a+a+a

so, here we get  5sides

now, 1.5*5 is 7.5

or 1.5+1.5+1.5+1.5+1.5 will give 7.5 cm

So, hence answer is 7.5 cm
