plz give me solved answer plz​

Answer 1

Answer:

Step-by-step explanation:

If the triangle is equilateral than all its three sides are equal.

Therefore we will divide 21 by 3 i. e.

21 / 3 = 7

Each side = 7 cm

Now, with the formula 1/2*b*h

We found the following

Height = 10.5 cm

Base = 7 cm

So, the answer is 36.75 sq. cm
