a rectangular floor has dimension 9 m by 7 m. if a square carpet of side 5m is laid on the floor then what is the area of the floor which is not carpeted?​

Answer 1

Solution :-

→Area of rectangular floor= 9 m × 7 m = 63 m²

→ Area of square carpet = 5 m × 5 m =25 m²

→ Area of the floor which is not carpeted= 63 m² - 25 m² = 38 m²

Answer 2

$\huge\bf\color{lime}{Solution :-}$

$\small\red{\boxed{\sf{→\ Area\ of\ rectangular\ floor = 9 m × 7 m = 63 m²}}}$

$\small\red{\boxed{\sf{→\ Area\ of\ square\ carpet = 5 m × 5 m = 25 m²}}}$

$\small\red{\boxed{\sf{→ Area\ of\ the\ floor\ which\ is\ not\ carpeted = 63 m² - 25 m² = 38 m²}}}$

Hence, Area of not carpeted floor is 38m².
