Question

Find the length of diagonal of the rectangle whose sides are 16cm12m

Answer 1

Answer:

20 cm

Step-by-step explanation:

To find this answer you must use the Pythagorean theorem.

= $a^{2} + b^{2} = c^{2}$

let length = a and breadth = b and diagonal = d

length = 16 cm = a

breadth  = 12 cm = b

$16^{2} + 12^{2} = d^{2}$

256 + 144 = $d^{2}$

400 = $d^{2}$

$\sqrt{400}$ = d

20 = d

d = 20cm
