Question

find the perimeter of the rectangle whose length is 24 cm and diagonal is 25 CM ans is 50
​

Answer 1

Answer:

Step-by-step explanation:

It is given that,

Length = 24 cm.

Diagonal = 25 cm.

Consider the breadth of a rectangle = b m.

Using Pythagoras theorem in triangle ABC,

AC

2

=AB

2

+BC

2

Substituting the values,

252=242+b

2

625=576+b

2

By further calculation,

b

2

=625–576=49

b=

49

​

=7 cm.

Here the perimeter of rectangle = 2(l+b)

Substituting the values,

=2(24+7)

So we get,

=2(31)

=62 cm.
