Question

a floor is 5m long and 4m wide. A square carpet of side 3.5m is laid on the floor. Find the area of the floor not carpeted. can anyone answer??

Answer 1

Area of rectangular floor = Length × Breadth = 5m × 4m = 20m²

Area of square carpet= Side² = (3.5m)² = 12.25m²

Area of the floor not carpeted= Area of rectangular floor-Area of square carpet

20m² - 12.25m² = 7.75 m²

Answer 2

Length=5m

Breadth=4m

Carpetarea=3.5sqm

Rectangle area=(l)(b)

so ,find the values on formula

=(5m)(4m)=20sqarea

so

20sq-3.5=16.50
