Answer» Answer: 30 m; AREA of Square is more by 100 sq. meter Step-by-step explanation: Length= 40cm Breadth= 20CM Perimeter of the RECTANGLE= Length of the WIRE =2(l+B)= 2(40cm + 20cm) =2×60cm = 120cm Now, the wire is rebent into a square. Perimeter= 120cm 4*side = 120 side = 120/4 = 30cm Area of rectangle = l*b = 40*20 = 800cm² Area of square = side² = 30² = 900 cm² 900 > 800 Hence, the square encloses 100m² more area than rectangle |
