is 12 cm.​

Answer 1

Answer:

length of diagonal is 37cm

Answer 2

Answer:

The length of the diagonal is 37 cm.

Step-by-step explanation:

The triangle formed by two sides of a rectangle and the diagonal is a right angled triangle.

In this right-angled triangle the diagonal is the hypotenuse.

Given:

length (l) = 35 cm

breadth (b) = 12 cm

Let the length of the diagonal be d.

Use Pythagoras theorem to determine the value of d as follows:

$d^{2}=l^{2}+b^{2}\\=35^{2}+12^{2}\\=1225+144\\=1369\\d=\sqrt{1369}\\=37$

Thus, the length of the diagonal is 37 cm.
