HELP PLSS IT'S VERY IMPORTANT

Determine the area of the composite figure.
Determine the perimeter of the composite figure.​​​​​

Answer 1

area = 255
`m^(2)`

perimeter = 20+6.7+8+8+15+26 = 83.7m

Explanation:

top left triangle - base is 3 because (20-8-9). so 1/2 bh = 1/2 (3) (6) = 9

left rectangle = l x w = 20 x 6 = 120

middle square = l x w = 8 x 9 = 72

lower right triangle = height is 12 because (26-8-6), so 1/2 bh =1/2 (9)(12) = 54

9+120+72+54 = 255
