**Upper primary school mathematics question UPQ368**

The figure below shows 2 identical regular hexagons overlapping each other. Each hexagon has an area of 216 cm^{2} each. Given that AB = BC, find the area of the yellow region.

Solution:

A regular hexagon is a 6 sided-ploygon that with each side equal in length and it is formed by 6 identical equilateral triangles

AB = BC, the overlapping area is area of 2 equaliteral triangles

The area of the hexagon = 216cm^{2}

The area of one equilateral triangle = 216 ÷ 6 = 36cm^{2}

The area of the yellow region = The area of 4 equilateral triangles = 4 × 36 = 144cm^{2}
