Question

Area of Rhombus:- 1/2 × Product of diagonals
formula .... please solve this for me plzz​ Q4.

Answer 1

Answer:

₹300.

Step-by-step explanation:

First find the area of each tile.

Area of each tile = 1/2 x 40 x 25

                             = 1/2 x 1000                

                            = 500 cm²

                           

Now, find the area of whole floor.

Area of floor = area of each tile x 1500.

                      = 500 x 1500

                      = 750000 cm².

                      = 75 m²

( 1m² = 10000cm²)

Cost of polishing floor:-

Area of floor = 75m²

Cost of polishing each m² = ₹4

Cost of polishing the whole floor = 75 x 4 = 300 rupees.

Answer 2

Answer:

• area=75,0000m^2

Step-by-step explanation:

area=1/2×40×25×1500=75,0000

cost=75,0000×4=30,00,000
