Question

find th area of an equilateral triangle with side 10 cm​

Answer 1

Answer:

Area of equilateral∆= (√3/4)*side²

Area of equilateral∆= (√3/4)*side²= (√3/4)*10² cm²

Area of equilateral∆= (√3/4)*side²= (√3/4)*10² cm²=(√3/4)*100 cm²

Area of equilateral∆= (√3/4)*side²= (√3/4)*10² cm²=(√3/4)*100 cm²= 25√3cm²

Answer 2

The area of equilateral triangle is 43.3 sq. cm.

Step-by-step explanation:

Since we have given that

Side of equilateral triangle = 10 cm

So, we need to find the area of equilateral triangle.

As we know the formula:

So, Area of equilateral triangle would be

$\dfrac{\sqrt{3}}{4}\times side^2\\\\=\dfrac{\sqrt{3}}{4}\times 10\times 10\\\\=43.3\ sq.cm$

Hence, the area of equilateral triangle is 43.3 sq. cm.
