Question

Find the area of the shaded region in the following figures​

Answer 1

Solution:

Let us find the area of the entire figure first and subtract the unshaded region area to find the area of the shaded region.

The given figure is of a square of side 25 cm.

Total area = 25²

=> 625 cm²

The shaded figure inserted is a rhombus.

Apart from this , we can observe four unshaded triangles of equal area.

Area of each individual triangle :

=> ½ × 5 × 20

=> 50 cm²

Area of 4 triangles ;

=> 200 cm²

Remaining area of the shaded figure :

=> 625 - 200

=> 425 cm² .

This is the required answer .
