Question

Find the area of the shaded region -

your answer should come 446cm²

Answer - 446cm²
​

Answer 1

Answer:

There seems to be a misprint in this particular question. As per the question, the answer should be 599.9846 m². But the length and breadth should have been 30cm and 20cm respectively to obtain the answer i.e. 446 cm².

However, I would be posting both scenarios. I would prefer you to choose the first scenario anyways.

Step-by-step explanation:

Scenario 1 (Assuming there's no misprint)

Area required = Area of Rectangle - (4 x area of a quadrant)

={(3000x2000)- 4(pi/4 x (7)^2)} square centimeters

= (6000000 - 154) square cm

= 5999846 cm² or 599.9846 m²

Scenario 2 (Assuming length and breadth to be 30cm and 20cm respectively)

Area required = Area of Rectangle - (4 x area of a quadrant)

={(30x20)- 4(pi/4 x (7)^2)} square centimeters

= (600 - 154) square cm

= 446 cm²

Hopefully, I was able to cover up your doubt.
