Question

A wire is in the shape of a square of perimeter 64 cm. A rectangle is formed with this wire
such that its length is 20 cm. Then, the area of the rectangle is
​

Answer 1

Answer:

256 sq. cm

Step-by-step explanation:

perimeter of square =4a

                                   64=4a

                                  64/4=a

                                  16=a

area of square =area of rectangle

a^2=area of rectangle

16^2 =area of rectangle

256=area of rectangle

therefore area of rectangle = 256 sq. cm

Answer 2

Answer:

A wire is in shape in square of perimeter=64cm

it's length is=20cm

formula=length×bredth

=64×20

=1280

the area of rectangle=1280
