Question

a wire is in the shape of square of side 12cm .if the wire is rebent into a rectangle of length 14cm ,find its breadth .which figure encloses more area and by how much?

Answer 1

Hello mate,

Here is your answer,

-------------------------------------------------------------------------------------------------

Side of the square = 12

Perimeter = 12 * 4 = 48 cm

Perimeter of square = perimeter of rectangle

2 ( l + b) = 48

14 + b = 24

b = 10 cm

Area of square = 12 * 12 = 144 cm2

Area of rectangle = 10 * 12 = 120 cm2

Therefore, area of  square is more by (144-120)=24 cm2

HOPE THIS HELPS UU :)

AND STAY BLESSED.

Answer 2

Answer:

Step-by-step explanation:

Side of the square = 12

Perimeter = 12 * 4 = 48 cm

Perimeter of square = perimeter of rectangle

2 ( l + b) = 48

14 + b = 24

b = 10 cm

Area of square = 12 * 12 = 144 cm2

Area of rectangle = 10 * 14 = 140 cm2

Therefore, area of  square is more by (144-140)=4 cm2 answer
