Answer:
10. 60 in^2
11. 27 cm^2
12. 24 cm^2
13. 4 in^2
14. 24 cm^2
Step-by-step explanation:
The applicable formulas are ...
trapezoid area: (1/2)(b1 +b2)h
triangle area: (1/2)bh
rectangle area: bh
square area: s^2
where b, b1, b2 are base lengths, h is height, s is side length.

Fill in the numbers and do the arithmetic.
10) A = (1/2)(10 +14)(5) = 60 . . . in^2
11) A = (1/2)(6 cm)(9 cm) = 27 cm^2
12) A = (8 cm)(3 cm) = 24 cm^2
13) A = (2 in)^2 = 4 in^2
14) A = (1/2)(9 +7)(3) = 24 . . . cm^2
Answer:
Step-by-step explanation:
let the speed of stream=x mi/hr
then (3+x)t=5
and (3-x)t=0.5
or
3t+xt=5
3t-xt=0.5
add
6t=5.5
t=5.5/6 hr
(3+x)t=5
3+x=5/t=5×6/5.5=6/1.1
x=6/1.1-3=(6-3.3)/1.1
x=2.7/1.1 /approx 2.45 miles/hr
