Fill in the blanks to make the statements true:

The sum of areas of two squares with sides 4a and 4b is ………………. .

16(a2 + b2)

Given:- side of first square = 4a


⇒ Area of first square = (side)2


= (4a)2


= 16a2


side of second square = 4b


⇒ Area of second square = (side)2


= (4b)2


= 16b2


Sum of areas of the two squares = 16a2 + 16b2


= 16(a2 + b2)
