Question

please solve my problem

Answer 1

side given = 30 cm
formula of area of equilateral triangle = root 3/4* (side)^2
area = root 3 /4* (30)^2
= root 3/4 *900
= root 3*225

Answer 2

area of triangle =$\frac{1}{2}$bh
since it is an equilateral triangle the b=h=30cm

therefore; area = $\frac{1}{2}$*30*30
                         =450
