Question

Find the length a diagonal of an rectangle having sides 11cm and 60cm

Answer 1

61 cm is the length of diagonal by using Pythagoras theorem

Answer 2

length =11 cm
breadth = 60 cm
through Pythagoras theorem
${cd }^{2} = {bc }^{2} + {cd}^{2} \\ {cd}^{2} = {60}^{2} + {11 }^{2} \\ {cd }^{2} = 3600 + 121 \\ {cd}^{2} = 3721 \\ cd = \sqrt{3721 } \\ cd = 61$
therefore, diagonal of the rectangle is 61cm
