Question

Find length of rectangle having breadth 8 units and diagonal 17units. *​

Answer 1

Answer:

15

Step-by-step explanation:

Answer 2

Answer:

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

$17 = \sqrt{ { l}^{2} + {8}^{2} }$

${17}^{2} = {l}^{2} + {8}^{2}$

$289 = {l}^{2} + 64$

$289 - 64 = {l}^{2}$

$225 = {l}^{2}$

$\sqrt{225} = l$

$15 = l$

Hence, Length = 15 cm
