Find the area and perimeter. Stuck on this one need help
masya89 [10]

9514 1404 393

Answer:

  • area: 114 square units
  • perimeter: 44 units

Step-by-step explanation:

The figure is a trapezoid with bases 12 and 7, and a height of 12. The area formula is ...

  A = (1/2)(b1 +b2)h

  A = (1/2)(12 +7)(12) = 114 . . . square units area

__

The length of side AB can be found using the distance formula:

  d = √((x2 -x1)^2 +(y2 -y1)^2)

  d = √((6 -(-6))^2 +(1 -6)^2) = √(144 +25) = 13

The sum of the side lengths is then ...

  13 +7 +12 +12 = 44 . . . units perimeter
