Question

find the area of a rectangular field whose side is 75m 5dm and 120m​

Answer 1

The area of the field is 15000 m².

Explanation:

1 meter = 10 decca meter

∴ 75 meter 5 decca meter = 75.0 + (5×10) meter

                                      = 75 + 50 meter

                                      = 125 meter

∴ We get,

Length of the rectangular field = 125 meter

Breadth of the rectangular field = 120 meter

∴ Area of the rectangular field = ( Length × Breadth)

                                                 = (125 × 120) m²

                                                 = 15000 m²

 ∴ The area of the field is 9060 m².
