Question

find the area if the digonal of a rectangle is 34 and breadth is 16

Answer 1

Answer:

Let the length of the rectangle =l cm

The diagonal of a rectangle divides it into two equal right

angled triangles. Hence, diagonal forms the hypotenuse of a right angled

triangle, with the other two sides being the length and breadth of the

rectangle.

Hence, diagonal =

l

+16

=34cm

=>l

2

+256=1156

=>l=

1156−256

=

900

=30cm

Answer 2

Answer:

length =√(d²-b²)

length=√(1156-256)

length=√900

length=30

area =length×breadth=16×30=480
