Answer 1

Answer:

P=46cm

Length

15 cm Diagonal 17

P=2(l+w)

d=w2+l2

Solving forP

P=2l+2d2﹣l2=2·15+2·172﹣152=46cm

Answer 2

length=15, height=diagonal

length sq +base sq= height sq

15 sq+ b sq =17 sq

225 +b sq = 289

b sq = 64

b = 8

area of rectangle= 15 *8 = 120 m sq

perimeter of rectangle= 2(15+8)

=2*23

= 46 c.
