solve it
you have 24 hours

Answer 1

Hey mate, here is your answer!

First of all, we find out the area of the whole portion.

since it is a rectangle, area = l x b
=> 24 x 18 = 432

Now, area of shaded portion =
total Area - area of unshaded part.

=> total Area - [area of the 3 triangles]
=> total Area -[ (1/2 x 12 x 12) + (1/2 x 12 x 12) + ( 1/2 x 24 x 12)
=> 432 - (72+72+144)
=> 432 - 288
=> 144 unit ^2

Answer 2
