Please help me with this and explain

9514 1404 393

Step-by-step explanation:

The perimeter is the sum of the side lengths. Those that are unmarked are assumed to match the length of the nearest parallel side.

Clockwise from upper left, the perimeter is ...

  P = 8 + 5 + 4 + 4.5 + 15 + 5.6 + 4 + 5

  P = 51.5 . . . feet

__

The area can be figured using the formulas for area of a parallelogram, rectangle, and trapezoid. These are, respectively, ...

parallelogram area = (8 ft)(3 ft) = 24 ft²

rectangle area = (8 ft)(4 f) = 32 ft²

trapezoid area = (1/2)(8 ft +15 ft)(4 ft) = 46 ft²

Then the total area of the figure is ...

  A = 24 ft² +32 ft² +46 ft²

  A = 102 ft²

Additional comment

The figure shown is impossible. The trapezoid side lengths and height are consistent with a bottom base of length 14, not 15.

i belive those are the ones that are under 90 degreese.
