=

400+225

=

625

=25cm

Answer 2

Answer:

suppose the rectangle is ABCD

rectangle property : all angles are 90°

therefore,angle A=B=C=D=90°

we know that,

every diagonal of a rectangle is hypotenuse.

let this (hypo)be "x"

by pythagoras theorem,

(hypo)^=(side1)^+(side2)^

(x)^=(20)^+(15)^

(x)^=(400)+(225)

(x)^=625

X=√625

X=25
