Question

the length of the diagonal of a rectangle is 10 cm that of one side is 8 cm. What is the area of the rectangle?

Answer 1

If we consider diagonal as hypotenuse and one side as base of triangle
Then, altitude=10^2 - 8^2
=100-64
=36
square root of 36 is 6.
then length is 8 and breadth is 6
so, area is 8*6=48cm^2

Answer 2

Answer:

If we consider diagonal as hypotenuse and one side as base of triangle

Then, altitude=10^2 - 8^2

=100-64

=36

square root of 36 is 6.

then length is 8 and breadth is 6

so, area is 8*6=48cm^2
