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 !
