Question

If the adjacent sides of a rectangle are 6cm and 8cm ,find the length of the remaining sides ​

Answer 1

Area of rectangle = (8×6)=48 cm

2

Perimeter of rectangle = 2(8+6) = 28 cm

Let the side of square be a

Therefore, perimeter = 4a

Perimeter of square = Perimeter of rectangle

⇒4a=28

⇒a=7 cm

Therefore, area of square = 7

2

= 49 cm

2

Therefore, difference between area of square and area of rectangle=(49−48)=1 cm
