Question

Find the perimeter of a rectangle in which diagonal is 10 cm long and one side is 6 cm long​

Answer 1

Answer:

28 cm

Step-by-step explanation:

Perimeter is the sum of all the sides of any geometrical object.

As the parallel sides of rectangle are equal, therefore its perimeter = 2(length) + 2(height)

Now take 6cm to either length or height.

Then a triangle would be formed, actually a right triangle have hypotenuse as 10cm and say length as 6cm, now use Pythagoras theorem ,

10²= 6²+A²

A= 8cm

Then put it in the above equation of perimeter.

Perimeter= 2(6)+2(8)

Perimeter = 28cm

Answer 2

Answer:

28

Step-by-step explanation:

Perimeter is the sum of all the sides of any geometrical object.

As the parallel sides of rectangle are equal, therefore its perimeter = 2(length) + 2(height)

Now take 6cm to either length or height.

Then a triangle would be formed, actually, a right triangle has hypotenuse as 10cm and say length as 6cm, now use Pythagoras theorem,

A= 8cm

Then put it in the above equation of perimeter.

Perimeter= 2(6)+2(8)

Perimeter = 28cm
