What is the area of equilateral triangle whose length is 203 CM

Answer»

Answer:

20604.5{cm}^{<klux>2</klux>}

Simplified Step by Step:

Method 1

1)Cut the equilateral triangle into 2 halves.

2) Get the area of 1 half. The base is just half of 203cm since it's an equilateral triangle and all SIDES have same length.

\frac{1}{2} \times \frac{203}{2}(base) \times 203(height) = 10,302.25

3) Now that you have obtained 1 half, add both halves and you get the answer.

Method 2

1) Since it's a triangle, the formula half times base times height applies.

Hence

\frac{1}{2} \times 203 \times 203 = 20604.5
