Question

an equilateral triangle is drawn over a square of side 4 cm. find the perimeteof the figure.​

Answer 1

(4x3) cm= 12cm

Step-by-step explanation:

In an equilateral triangle,all the sides are equal.

The triangle shares a common side with a square.

Length of side of square (l)= 4cm = length of side of the triangle.

Perimeter of a triangle= (L1 + L2 + L3)

Since, l=L1 =L2 =L3,

Therefore, perimeter of given triangle= 3xl = (3x4) cm

= 12 cm
