### Kathryn's Homework 3,7,11

3)

a) 420 m. I added the length and width .

b) a²+ b²=c²
300²+120²=c²
(300X300)+(120X120)=c²
90000m²+14400m²=c²
104400m²=c²

√104400m²=c
323.10m=c

c) 420m-323.10= 97.10 m
Maria walked farther by 97.10 meters.

7)

a²=c²-b²
a²=80²-79²
a²=(80X80)-(79X79)
a²=6400cm²-6241cm²
a²=159cm²
a=√159cm²
a=12.61cm

11)

The maximum length of the ladder is 291.71cm and the minimum length is 291.10.
