Question

A wire is in the shape of a square of side 10cm. If the wire is rebent into a rectangle of length 12cm, find its breadth. Which figure encloses more area and by how much.

Answer 1

8 cm is the breadth.rectangle encloses more area of 96cmsquared

Answer 2

$\huge{ \mathbb{ \red{Answer}}}$





Side of square : 10 cm (given)

so, perimeter of square : 10 ×4 = 40cm


length of the rectangle: 12cm (given)

let the breadth of the rectangle : b

so, 2(l+b)=perimeter

2(12+b)= 40

24+2b=40

2b=40-24

2b=16

b= 16/2

b= 8cm


Now ,

Area of square : side ×side

=10×10 = 100 cm^2


and ,

Area of rectangle : lenght × breadth

=12×8=96cm^2

=> Difference in area = 100-96= 4cm^2


=> Hence the square encloses more area by 4cm^2
