Step-by-step explanation:

just imagine your copy the longest line is slanting line between two corners

This can be find by using pythagoras theorm

pythagoras theorm :

a^2 + b^2= c^2

c=root (a^2 + b^2)

a=3

b=4

putting a and b in the formula

(3)^2 + (4)^2= c^2

9+16=c^2

25=c^2

c=root 25

c=5 Ans
