NCERT Figure it Out 3 - Q2 - Area
Question: ABCD is a rectangle 18 cm by 10 cm with shaded regions as in the book (inner cuts marked 10 cm, 8 cm, 6 cm, 4 cm). Find a consistent shaded area by subtracting unshaded rectangles from the outer rectangle (illustrative dissection matching those lengths).
Answer: 92 cm^2 (for the dissection that removes an 8 by 6 and a 4 by 10 unshaded pair from 18 by 10). Match your book shading if labels differ.
