Question

The perimeter of an equilateral triangle is 48m. If area is

(a) 64 √3 m2

(b) 144 √3 m2 (c) 16 3 m2

(d) 256 √3 m2​

Answer 1

Answer:

Perimeter = 48

=> 3a = 48

=> a = 48/3

=> a = 16

Now, area of an equilateral triangle = {(root3)/4} × a^2

=> area = {(root3)/4} × 16×16

=> area = 64root3 [option (a)] ans.
