Answer 1

$\huge\mathbb{\purple{Answer ♡ }}\star{}$

The area of square is 49cm

The side of square is √49 =7cm

The perimeter of square is 4×7=28

⟹ The perimeter of rectangle is 28

The length of rectangle is 9.3cm

The breadth of rectangle is 2(9.3+b)=28

9.3+b=14

b=14−9.3

b=4.7cm

Area of rectangle is 4.7×9.3=43.71 cm

The square has greates area.

The area of square is 49cm

The side of square is √49 =7cm

The perimeter of square is 4×7=28

⟹The perimeter of rectangle is 28

The length of rectangle is 9.3cm

The breadth of rectangle is 2(9.3+b)=28

9.3+b=14

b=14−9.3

b=4.7cm

Area of rectangle is 4.7×9.3=43.71 cm

The square has greatest area.
