Question

length of a rectgular field is 12km and breadth 9km find length of its diagonal ​

Answer 1

Answer:

$length \: of \: diagonal = \sqrt{ {12}^{2} + {9}^{2} } = \sqrt{144 + 81} = \sqrt{225} = 15 \: \: km.$

Step-by-step explanation:

$length \: of \: diagonal = \sqrt{ {12}^{2} + {9}^{2} } = \sqrt{144 + 81} = \sqrt{225} = 15 \: \: km.$

Answer 2

Length of diagonal= √l² + b² = √(12km)²+(9km)²

= √144km²+81km²= √225km²= 15km.
