a) 20 cm
a2 + b2 = c2
a2=12cm=144cm
b2=16cm=256cm
c2=?=?
144cm+256cm=c2
144cm+256cm=400cm
c2=20cm
400's square root is 20cm.
b) 34 cm
p2 + q2 = r2
p2=16m=256m
q2=30m=900m
r2=?=?
256m+900m=r2
256m+900m=1156m
r2=34cm
1156's square root is 34cm.
Question # 4.
a) 9.2 cm
x2 + y2 = z2
x2=6cm=36cm
y2=7cm=49cm
z2=?=?
49cm + 36cm = z2
49cm + 36cm = 85
z2 = 9.2 cm
85's square root is 9.2 cm.
b) 13.6 cm
b2 + c2 = d2
b2=8cm=64cm
c2=11cm=121cm
d2=?=?
64cm + 121cm = d2
64cm + 121cm = 185cm
d2=13.6cm
185's square root is 13.6 cm.

goodjob Kathleen but i was kind of confused at question 3 because i didn't know the question so you should put that in but than that your scribe was very good.
i agree with kamille on question 3.
and also on question 4.. you lost me there. shouldnt it be like :
a)
x² + y²= z²
6² + 7²= z²
(6x6) + (7x7) = z²
36 + 49 = z²
85 = z²
√85 = √z²
9.2 = z²
kk, i wont put part b, because ill let you do do it yourself part a, was just an example.
