1.	8. The area of a square field with side 45 m isthe same as the area of a rectangular field withbreadth 25 m. Find the length and perimeter ofthe rectangular field.
Answer» Answer: length of the RECTANGULAR FIELD is 81m Perimeter of the rectangular field is 212m Step-by-step EXPLANATION: Area of the square field = 45 m x 45 m = 45x45 $m^2$ Let's assume that the length of the rectangular field is x According to the problem: $25x = 45^2$ ∴ $x = \frac{45 . 45}{25} m = <klux>81</klux> m$ ∴ Perimeter of the rectangular field $= 2 (length + breadth)$ = 2(81 + 25) m = 212 m
