Answer 1

We have to find area of shaded portion means the area of both the triangles.

Area of triangle = ½×base×height

Base is 3

All sides of square are equal so height is 12

½×3×12 = 18cm²

Area of one triangle is 18 so area of both the triangle is 18 cm² + 18cm² = 36cm²

So, Area of shaded part is 36 cm²
