Question

Looking for help finding the area to show work

Answer 1

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
