Area of rectangle = Length × Width
Calculation:
Given Figure:
As we can see side length of the figure is (a + b) and width is (a + b)
Area of figure = Length × width = (a + b) × (a + b) = (a + b)2 ..... (1)
Now,
Area of figure = Area of section 1 + Area of section 2 + Area of section 3 + Area of section 4
= a × a + a × b + b × a + b × b
= a2 + 2ab + b2
∴ (a + b)2 = a2 + 2ab + b2
