Answer 2

Answer:-

• Width of rectangle = (2√11)cm

Given:-

• Diagonal of rectangle = 12cm
• Length of rectangle = 10cm

To Find:-

• Width of rectangle = .....?

Solution:-

As we know that,

$digonal \: of \: rectangle = \sqrt{ {l}^{2} + {b}^{2} }$

${(daigonal)}^{2} = {(length)}^{2} + {(width)}^{2}$

${(12)}^{2} = {(10)}^{2} + {(width)}^{2} \\ 144 = 100 + {(width)}^{2} \\ {(width)}^{2} = 144 - 100 \\ {(width)}^{2} = 44 \\ width = \sqrt{44} = 2 \sqrt{11} \: cm$

Hence the width of rectangle is $2 \sqrt{11} \: cm$
