Question

a square and a rectangular field has the same perimeter. the dimensions of rectangular field are 120m into 90m . find out the which field has the greater area​

Answer 1

Step-by-step explanation:

Length = 24.5 m

Breadth = 18 m

   

   ∴ Area of the rectangle = Length × Breadth

                                 = 24.5 m × 18 m

                                 = 441 m2

              

  (ii) Length = 12.5 m

Breadth = 8 dm = (8 × 10) = 80 cm = 0.8 m     [since 1 dm = 10 cm and 1 m = 100 cm]

      

      ∴ Area of the rectangle = Length × Breadth

                                    = 12.5 m × 0.8 m

                                    = 10 m2
