Question
The sum of areas of two squares with sides 4a and 4b is ______.
Solution
The sum of areas of two squares with sides 4a and 4b is 16(a2 + b2).
Explanation:
∵ Area of a square = (Side)2
∴ Area of the square whose one side is 4a = (4a)2 = 16a2
Area of the square with side 4b = (4b)2 = 16b2
∴ Sum of areas = 16a2 + 16b2 = 16(a2 + b2)
