Answer 1

Answer:

d=13m

Have a nice day!

Answer 2

the angle between two adjacent sides of a triangle is 90 degree

so in rectangle ABCD . the diagonal AC is equal to

by Pythagoras theorem:

AC^2 = AB^2 + BC^2

AC^2 = 12². + 5²

AC². = 144+ 25

AC². = 169

AC = 13m

the length of the diagonal of the rectangle with side 12m and 5m is 13 m
