Answer 1

Step-by-step explanation:

Given :

• length of floor = 5m

• width of floor = 4m

• A square carpet of side 2m is laid on the floor.

To Find :

• The area of the floor that is not carpeted is

Solution :

Concept :

Measure the length and the width of a square or rectangular room.

Use the standard 2(Length + Width) = Perimeter formula tofind the perimeter of a room.

• Using a measuring tape, find the length and width of the room.

• Add the length and the width, then multiply the answer by two.

____________________________

Area of floor = l × b

• Substitute all Values :

A rea of floor = 5 × 4

A rea of floor = 20m²

Each side of square carpet = 2m

Area of square carpet that's laid on floor = side²

• Substitute all values :

Area of square carpet floor = 2²

Area of square carpet floor = 4m²

so, Areea of the floor that is not carpeted = Area of floor - area of carpet laid on floor

• Substitute all Values :

= (20 - 4)m²

= 16m²

• Hence the answer is 16m²
