Find the area of each figure. (Or as much as u can)

9514 1404 393

  7. 91 m²

  8. 56 in²

  9. 105 in²

  10. 135 m²

Step-by-step explanation:

The formula for the area of a triangle is ...

  A = 1/2bh

where b is the base length, and h is the height perpendicular to the base.

The formula for the area of a trapezoid is ...

  A= 1/2(b1 +b2)h

where b1 and b2 are the lengths of the parallel bases, and h is the perpendicular distance between them. Note that this formula is virtually identical to the triangle formula, with the triangle 'b' being replaced by (b1+b2).

Fill in the numbers and do the arithmetic. The result is shown in the attachment. (We have used the triangle formula for all, with b1+b2 being used for 'b' to find the area of the trapezoids.)

  7. A = 1/2(14 m)(13 m) = 91 m²

  8. 56 in²

  9. A = 1/2(14 +16 in)(7 in) = 105 in²

  10. 135 m²
