Question

Perimeter of an equilateral triangle is 60cm find area of triangle with diagrams

Answer 1

Answer:

very very very easy question.

Step-by-step explanation:

Perimeter =60 cm,

then side = perimeter/3 = 20 cm.

and area of an equilateral triangle,

=√3(side)²/4,

then the area

= √3* 20* 20/4

= 100* √3,

which approximately,

=100* 1.7

= 170 cm² (approx.)
