The shaded part is four little blocks, and its area is ' 1 '. So the area of each little block is 1/4 .
The part with crosses covers two little blocks. So its area is (2 x 1/4) = 1/2 .
To calculate the area of shapes, it's essential to break them into smaller parts, applying specific formulas for squares and triangles. For instance, the area of a square is calculated as A = s 2 and a triangle uses A = 2 1 bh . Mastering these concepts enables systematic problem-solving in mathematics.
