Answer 2

Solutions :-

Given :
Length of rectangular room = 14 m
Breadth of rectangular room = 10 m


Find the area of rectangular room :-

Area of rectangle = (Length × Breadth) sq. unit
= (14 × 10) m²
= 140 m²


Find the number of tiles needed :-

1 m² = 1 tiles
140 m² = (1 × 140) tiles


Hence,
Number of tiles needed = 140
