Answer 1

hope it helps you!!!!!!

Answer 2

$\huge{\underline{\underline{\bf{Solution}}}}$

$\rule{200}{2}$

$\tt given\begin{cases} \sf{Length \: of \: the \: rectangle \: is \: 4 \: cm.} \\ \sf{Breadth \: of \: the \: rectangle \: is \: 3 \: cm} \end{cases}$

$\rule{200}{2}$

$\Large{\underline{\underline{\bf{To \: Find :}}}}$

We have to find the Diagonal of the rectangle.

$\rule{200}{2}$

$\Large{\underline{\underline{\bf{Explanation :}}}}$

We know that,

$\Large{\star{\boxed{\sf{(Length)^2 + (Breadth)^2 = (Diagonal)^2}}}}$

_______________[Put Values]

$\sf{→(4)^2 + (3)^2 = (Diagonal)^2} \\ \\ \sf{→Diagonal = \sqrt{16 + 9}} \\ \\ \sf{→Diagonal = \sqrt{25}} \\ \\ \sf{→Diagonal = 5} \\ \\ \sf{\therefore \: Diagonal \: of \: rectangle \: is \: 5 \: cm}$
