Hence proved the question

Answer 2

Answer:

The area of the rectangle is = 60 m^2

Step-by-step explanation:

The length of the rectangle = 12 m

And the diagonal of the rectangle = 13 m

Now we have to find the area of the rectangle, so first we have to find the breadth of the rectangle

And we know, for rectangle,

Length^2 + breadth^2 = diagonal^2

So, for the given rectangle,

=> 12^2 + breadth^2 = 13^2

=> breadth^2 = 13^2 -12^2=169-144=25

=> breadth = √25 = 5 m

So, the breadth of the rectangle is = 5 m

And the length of the rectangle is= 12 m

So the area of the rectangle is = 5×12 = 60 m^2
