Solution
Step 1: Draw a line with a point which divides 6x,5 Step 2: Total distance of this line =6x+5 Step 3: Now we have to find out the square of 6x+5 i.e., Area of big square, ABCD=(6x+5)2 Step 4: From the diagram, inside square red and yellow square, be written as 36x2,52 Step 5: The remaining corner side will be calculated as rectangular side = length × breadth =6x×5 Therefore, Area of the big square, ABCD= Sum of the inside square +2 times the corner rectangular side. (6x+5)2=36x2+52+60x Hence, geometrically we proved the identity (6x+5)2=36x2+52+60x.
