Question

K. Find the area (A) and the perimeter (P) for each of the
following rectangle
(ii) Diagonal = 10 cm, breadth = 6 cm.​

Answer 1

Answer:

Length of rectangle = √100-36=√64=8 cm

then area =Lb

8(6) = 48.

perimeter= 6+6+8+8=28

Answer 2

Answer:

28cm

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
