Answer:
$ 34, 34
Step-by-step explanation:
1800 mm = 1, 8 m
1200 mm = 1, 2 m
A = 1,2 × 1,8 = 2, 16 m²
1 m² ..................... $ 15.90
2, 16 m² .............. $ x
x = 2,16×15,90/1 ≈ $ 34, 34
Yo sup??
lenght of sheet=1800mm=1.8m
breadth of the sheet=1200mm=1.2m
Area of sheet=1.2*1.8=2.16 m^2
Price of 1 m^2=15.9
therefore price of required sheet=2.16*15.9
=34.344
=34.34 (approx)
Hope this helps
