Answered by Saph

Answer: 82m

Step-by-step explanation:

hypothenuse theorem

29²-20²= 441

√441 = 21m

perimeter

21 + 21 + 20 + 20 = 82m

Saph: for you to find the diagonal, you have to use phytogoras' theorem... a^2+b^2=c^2. the diagonal is given, so a^2=c^2-b^2.

=perimeter of rectangle=
$2 \times (x + y)$
2*(20+29)
=2*49
= perimeter of rectangle = 98m

Saph: 29 is the diagonal

Saph: 29 is not the length
