Answer:
Area of rhombus = 1/2 d1×d2
Step-by-step explanation:
1/2×-25×12=300.5
300.5 × 200= 60, 100
The cost of polishing the floor is 400×300.5= Rs 1, 20, 200

Answer:
Area of rhombus= 1/2× diagonal ×diagonal×200
= 1/2× -25cm×12cm×200
=1/2× -60000
= -30000 m square
Cost of polishing the floor
1m square = Rs. 40
-30000 = ?
=-30000×40
=Rs. -12,00,000
