Question

. If its permeter of a equilateral triangle is 180 cm what will be the area​

Answer 1

Step-by-step explanation: Perimeter of △ABC= 180cm. So the side of an equilateral triangle is 60cm. Area of the equilateral triangle is given as Area = √34x2 where x is the side of the equilateral triangle. Hence the area of the triangle is 1558.84cm².

Answer 2

Answer:

perimeter of a equilateral triangle=3×side=180

=> side=180/3=60

side of the equilateral triangle is 60 cm

area of the equilateral triangle=√3/4.(side)^2

=√3/4×60×60 sq cm

=900√3 sq cm
