Answer:

10. 60 in^2

11. 27 cm^2

12. 24 cm^2

13. 4 in^2

14. 24 cm^2

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
