Answer 1

Step-by-step explanation:

area of equilateral triangle = √3/4× a²

= √3 /4 ×4x²

= √3x²

Answer 2

Step-by-step explanation:

Formula for area of equilateral triangle=

√3/4×s²

Side of the triangle=2x

Area of triangle=

=√3/4×(2x)²

=√3/4×4x²

=x²√3

Hence, area of the triangle is x²√3 cm²
