Question

Calculate the length of the diagonal of a rectangle whose sides are 20 cm and 6 cm

Answer 1

We have,

Length of rectangle $=20cm.$

Width of rectangle $=6cm.$

Then,

Diagonal of rectangle

$D=\sqrt{Widt{h}^2+Lengt{h}^2}$

$D=\sqrt{{20}^2+6^2}$

$D=\sqrt{400+36}$

$D=\sqrt{436}$

$D=2\sqrt{109}$

Hence, this is the answer.
