Answer 2

Answer:

80 cm^2

Step-by-step explanation:

let a = 10 cm

consider triangle abc of length 8 cm

so area of equilateral triangle = √3/4a2

=√3/4x8x8

=16√3 cm2

area of triangle = 1/2xbasexh

16√3=1/2x8xh

16√3x2x1/8=h

4√3 cm = h

area of parallelogram = base x height

area of parallelogram = 10x4√3

area of parallelogram = 40√3
