Answer 1

Answer:

The area of rectangle is 16 cm.

Answer 2

Answer:

Perimeter of square =16cm

Perimeter of rectangle =24cm

Area of square= 16cm

Area of rectangle=32cm

Step-by-step explanation:

Perimeter of square= 4×4 =16cm

Perimeter of rectangle= 2(8+4) =24cm

Area of square = 4×4= 16cm

Area of rectangle= 8×4=32cm

In the second part of question,

Area of floor = 16m ×12m =192m²

The cost of laying 1sqm is 80 ruppes

Therefore the cost of laying 192m² = 192×80

= Rs 15360
