Question

4. Find the measure of the diagonal of a rectangle whose length is 24 cm and
breadth is 7 cm?​

Answer 1

$length \: of \: rectangle \: or \: l = 24cm \\ breadth \: of \: rectangle \: or \: b = 7cm \\ to \: find \: diagonal \: or \: d \\ we \: know \: d = \sqrt{ {l}^{2} + {b}^{2} } \\ = \sqrt{ {24}^{2} + {7}^{2} } \\ = \sqrt{576 + 49} \\ = \sqrt{625} \\ = 25 \\ hence \: diagonal = 25cm$

Answer 2

Question ::-

Find the measure of the diagonal of a rectangle whose length is 24 cm and breadth is 7 cm?

Given ::-

• length of rectangle = 24 cm

• Breadth of rectangle = 7 cm

To find ::-

• Diagonal of rectangle ?

Solution ::-

• Length = 24 cm (l)

• Breadth = 7 cm (b)

• Diagonal = D

_________

$\: \: \: d \: \: \: = \sqrt{ {l}^{2} + {b}^{2} }$

$\: \: \: d \: \: \: = \sqrt{ {24}^{2} + {7}^{2} }$

$\: \: \: d \: \: \: = \sqrt{ 576 \: \: + \: \: 49}$

$\: \: \: d \: \: \: = \sqrt{625}$

$\: \: \: d \: \: \: = 15$

__________

• Diagonal of rectangle 15 cm
