Question

The perimeter of rectangle whose length is 60 cm and a diagonal is 61 cm is​

Answer 1

Answer:

The length of rectangle = 60

The breath of rectangle = 61

The perimeter of rectangle = 2(l + b)

= 2(60+61)

= 2*121

= 242

Answer 2

Answer:

142 cm

Step by step explanation:

At first divide the rectangle by joining its diagonals

Therefore you will find two triangle formed.

Now apply the pythagoras theorem

and then

or, h^= 61^ - 60^

or, h^= (61+60) (61-60)

or, h^=121×1

or, h^=121

or, h= root over 121

or, h=11 cm

Therefore, p( perimeter)=2(l+b) unit

p=2(60+11) cm

p=142cm (Ans)
