Answer 1

Step-by-step explanation:

rectangle ABCD, let BC be the breadth with length 8cm and

AC be diagonal of length 17cm.

In the right angled triangle ABC,

Length AB= AC2−BC2−−−−−−−−−−√=172−82−−−−−−−√=15cm

Area of the rectangle=l*b=15*8=120cm^2

Perimeter of the rectangle=2(l+b)=2(15+8)=46cm
