Question

What is the length of the diagonal of a rectangle that is $8$ feet long and $15$ feet wide?

• A. $13$ feet
• B. $11$ feet
• C. $17$ feet
• D. $289$ feet

Answer 1

Answer: (C)

$17$ feet

Given, length $=8$ feet, width $=15$ feet

Diagonal length of a rectangle $=$ $\sqrt{l^2+w^2}$
$=$ $\sqrt{8^2+{15}^2}$
$=$ $\sqrt{64+225}$
$=$ $\sqrt{289}$
$=17$ feet
