Question

A Rectangular play ground is
diagonal length is 25 kilometers.
so that its
breadth is
7km. Find its
area​

Answer 1

Step-by-step explanation:

Let ABCD be the rectangle and AC be the diagonal as shown in the above figure:

It is given that the diagonal AC=125 m and length of AB=75 m

In △ABC, ∠B=90

0

According to the pythagoras theorem

AC

2

=AB

2

+BC

2

⇒125

2

=75

2

+BC

2

⇒15625=5625+BC

2

⇒BC

2

=15625−5625

⇒BC

2

=10000

⇒BC=

10000

⇒BC=

100

2

⇒BC=100

Hence, the length of the diagonal is BC=100 m.
