Question

what is the length of the diagonal of a 36cm by 48cm rectangle?​

Answer 1

Answer:

60 cm

Step-by-step explanation:

According to pythagoras thm:

c^2 = a^2 + b^2

c^2 = (48 × 48) + (36 × 36)

c^2 = 1296 + 2304

c^2 = 3600

c = √3600

c = 60

Answer 2

Hello Janu, your answer is 60 cm.

Step-by-step explanation:

Here , we are using the Pythagoras theorem which states that the square of the hypotenuse of a triangle is equal to the sum of the squares of the other two sides.

That is ; AB²+BC²= AC²

When we substitute the values ;

36²+48²=AC²

1296+2304= AC²

3600=AC²

AC=_/3600

AC=60

So , we found that AC is 60cm

The length of the diagonal is 60cm.

Hope this helps you !
