Question

The diagonal of a rectangle 12cm.What is the perimeter of figure formed by joining the mid points of the sides of rectangle in order?​

Answer 1

Answer:

24 cm

Step-by-step explanation:

The Rectangle has two diagonals, if one is 12 cm long then the other is also 12 cm long.

These two diagonals intersect at the middle i.e 2 halves 6 cm each.

Now, when we join the midpoints of the rectangle, we form a four sided figure  with sides parallel to the diagonals and corresponding to the inner half of the diagonals.

Therefore the figure formed has four side of length 6 cm each

hence its perimeter is 6*4=24cm

Answer 2

Answer:

24 cm

Step-by-step explanation:

the rectangle has two diagonals ,if one is 12 cm long then the other is also12 cm long

these two diagonals intersect at the middle I. e. 2 halves 6 cm each

now ,when we join the midpoint of the rectangle , we form a four sides figure with side parallel to the diagonals and corresponding to the inner half of diagonals

therefore the figure formed has four side of length 6 cm each

henceits perimeter is

$6 \times 4 = 24cm$
