Answer 1

Answer:

Hey mate☺

Step-by-step explanation:

Given is:- equilateral triangle

All sides of this triangle are equal

Let each side be x

x+x+x= 60

...as given 60cm as perimeter.

Perimeter:- Sum of all sides

x+x+x= 60

3x = 60

x= 60/3

x= 20

Hence, each side is 20cm

Area of triangle :-

= (1/2)×Height×Base

=(1/2)×20×20

=(1/2)×400

=400/2

=200cm²

Therefore area of Given triangle is :- 200cm²
