Find the blue shaded region I Math Olympiad

Geometry, the branch of mathematics that explores the properties and dimensions of shapes and spaces, often presents us with fascinating challenges that require creative thinking. In this blog post, we will embark on a geometric journey to uncover the area of the blue shaded region within a rectangular puzzle. As we delve into the problem, we will use our knowledge of basic geometric concepts and calculations to unveil the hidden beauty within this shape.

The Rectangular:

Let’s begin by understanding the key elements of the rectangular puzzle:

Length and Breadth of the Rectangle:

In the above rectangular

Length = FD=8

Breadth= BD=5

OM=1/2 *BD=2.5

ON=1/2 FD=4

AB= 7

CB=4

The area of rectangle

8*5=40

∆AOB + ∆BOC

Total area of white space

2(∆AOB + ∆BOC)

Calculating the Blue Shaded Region:

To find the area of the blue shaded region, we’ll start by calculating the areas of triangles AOB and BOC, and then subtracting this total from the area of the entire white space.
