Question

A wire in the in the form of an equilateral triangle of side 40 cm is converted into a square. find the area of the square to formed.​

Answer 1

Answer:

900sq.cm

Step-by-step explanation:

Side of equilateral triangle is 40cm.

Therefore, perimeter of the triangle or the total length of the triangle is

= 40+40+40

=3*40

=120cm

Using same length of wire a square is formed.

Therefore, perimeter of the square is equal to the length of the wire i.e. 120cm.

Perimeter of square=4*side

120=4*side

Side=120/4

Side=30cm

Now,

area of the square=side*side= 30*30

= 900sq cm
