Q.24 pointsQ2 A wire is in the shape of a rectangle. It's length is 40cm andbreadth is 20cm.If the same wire is bent to form a square, what isthe measure of its side. Also find which shape has more area and byhow muchO 120 m; Area of Rectangle is more by 100 sq. meter120 m; Area of Square is more by 100 sq. meter30 m; Area of Square is more by 100 sq. meterO 30 m; Area of Rectangle is more by 100 sq. meter​

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
