A rectangular floor is 10 m long and 3 m wide. A square carpet of sides 4 m is laid on the floor. Find the area of the floor that is not carpeted. Find The Area of the floor not Carpeted.
Answers
area not carpeted = area of floor - area of carpet
= 10*3 m - 4*4m
= 30-16
= 14m²
Answer:
Solution:
Length=10m
Breadth=3m
Are of the rectangle=l*b
=10*3
=30 square metre
Asquare carpet of side 4
Area of the square =a*a
=4*4
=16square m
The are of the floor that is not selected= 30-16 square m
=14 square m of floor is left out
_______________________________________
first, we have to find the area of the rectangular floor
area of a rectangle= length into breadth
therefore, the area of the floor- 10 m into
3 m 30 m square
next, we will have to find the area of the square carpet
area of a square= side into side
therefore, the area of the square carpet= 4 m into 4 m = 16 m square
therefore, the area of floor that is not carpeted= 30 m square- 16 m square= 14 m square
