Question

6. ABCD is a rectangle. Calculate the shaded area. ​

Answer 1

Answer:

18cm

I think so

Step-by-step explanation:

4cm+8cm+6cm

Answer 2

Answer:

Therefore, Area of the rectangle= 12 × 16 cm²

= 552 cm²

Therefore, Area of the Quadrilateral is-

As you can see it is a triangle above a rectangle.

Therefore, area of the inner quadrilateral-

= ½ × 6 cm × 4 cm

= 12 cm²

Therefore, area of the rectangle part of the inner quadrilateral = 6 cm × 4 cm

= 24 cm²

Thus, area of the inner quadrilateral = 12 + 24 cm²

= 36 cm²

Thus, Area of the shaded portion =

Area of rectangle - Area of the inner quadrilateral

= 552 cm² - 36 cm²

= 516 cm² (Answer)
