✴◾QUESTION ◾✴

Find the diagonal of a rectangle whose length is 12 cm and breadth is 9 cm.

✴◾SOLUTION ◾✴

GIVEN

• Length of Rectangle = 12cm.
• Breadth of Rectangle = 9cm.

TO FIND

• The Diagonal of Rectangle.

FORMULA

Length of diagonal = $\bold{\sqrt{l²+b²}}$

$\bold{\implies d =\sqrt{12²+9²}}$

$\bold{\implies d =\sqrt{144+81}}$

$\bold{\implies d =\sqrt{225}}$

$\bold{\implies d = 15}$
