Question

2. Find the area of an equilateral triangle with side 10 cm.

Answer 1

HERE ,

SIDE, S = 10 CM

AREA OF EQUILATERAL TRIANGLE = √3/4×S²

                                                            = √3/4×100

                                                            = 25√3 CM²

Answer 2

Solutions :

Given :

Side of equilateral triangle = 10 cm

Find the area of an equilateral triangle :-

Area of equilateral triangle = √3/4 (side)² square unit

= √3/4 (10)² cm²

= √3/4 × 100 cm²

= √3 × 25 cm² = 25√3 cm²

Hence,

Area of an equilateral triangle is 25√3 cm²
