Question

A new problem is attached

Answer 1

Since all equilateral triangles are similar to one another,
\(\triangle ABC \sim \triangle MNP\)

clearly, ratio of areas = \(4 : 1\)
th ofat gives, ratio of sides = \(2 : 1\)

Answer 2

area of traezium = 1/2 (a+b).h = rt3/4 a^2

Answer 3

AB : MN = 2 : 1
AB = 2*MN
MN = 20
