Question

the area of a square is 49sq cm rectangle has the same perimeter as the square if the length of rectangle is 9.3 what is its breadth

Answer 1

Area of square = 49 cm^2
=> a^2 = 49
=> a = 7 cm

Side of square = 7 cm

Perimeter of square = 4 *7 = 28 cm

Perimeter of rectangle = Perimeter of square
Perimeter of rectangle = 28 cm
=> 2(L+B) = 28
=> 9.3 + B = 14
=> B = 4.7 cm

Width of rectangle = 4.7 cm
