Answer 1

42^=1764
35×51=1785
1785-1764=21

Answer 2

solution :

Square
side of square = 42 m
Area of square = side × side {unit }
(42 × 42 ) m
1764m
● Area of square is 1764 meter
Rectangle
Length = 51m
Breadth = 35m
Area of rectangle = length × breadth {unit}
( 51 × 35 ) m
1785m
● Area of rectangle is 1785 metre .

Now compare the areas of both square and rectangle
Square Rectangle
1764m 1785m
◆ The area of rectangle is greater .
