Question

1. If the perimeter of a equilateral triangle is 180 cm. Then its area will be:
a. 900 cm²b. 900v3 cm’c. 300v3 cm’d. 600v3 cm’ ​

Answer 1

900 cm

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.
