Answer 1

$\huge{\underline{\mathcal{\red{A}\green{n}\pink{s}\orange{w}\blue{e}\pink{R:-}}}}$

➦ Length of diagonal = √L^2 + b^2

$\sqrt{ {l}^{2} } + \: {b}^{2} \\ \sqrt{ {10}^{2} } + \: {24}^{2} \\ \sqrt{100} + \: 576 \\ \sqrt{676 } \\ = \: 26cm$

Hence option c is correct Answer .

Answer 2

Answer:

the right answer is c) 26cm

Step-by-step explanation:

as the two side and a diagonal of rectangle made a right angle triangle

by using Pythagoras theorem

√{(24)^2 + (10)^2}

=√{ (24×24) + (10×10)}

=√{ 576+100}

=√ 676

= 26
