Sorry if some other person did this question already , but anyways here you go :)
page 110 .
# 3. Walter walks across a rectangular field in a diagonal line . Maria walks around two sides of the field . They meet at the opposite corner .
a) How far did Maria walk ?
120m + 300m = 420m . Maria walked 420m .
b) How far did Walter walk ? Express your answer to the nearest meter .
a2 + b2 = c2
3002m + 1202m = c2
( 300 x 300 ) + ( 120 x 120 ) = c2
90 000 + 240 = c2
c2 = 90 240 SQUARED .
c2 = 300.3m .
c ) Who walked farther ? By how much ?
Maria walked farther by 119.7 m .
there you go , please comment !
