Answer:

50 cm2

Step-by-step explanation:

An equilateral triangle has equal sides, so we divide 30 cm by 3 to get each side is 10 cm.

Then we use the formula for the area of a triangle.

\frac{1}{2} (b × h)

= 1/2 (10*10)

=1/2 of 100

=50

Answer:

under root 3 multiply 25

Step-by-step explanation:

perimeter=30 cm  = 3(sides)                                                                         side=30/3=10 cm                                                                                                area=sq.rt.3/4(side)^2                                                                                                         area=sq.rt.3/4 X 10^2                                                                                                                                 area=sq.rt.3/4 X 100                                                                                        area=sq.rt.3 X 25

area = 25(square root 3)
