Answer:
5: perimeter- 38 in (10+10+9+9) area- 80 in [(8x4.1)/2]+[(8x4.1)/2]+[5.9x8]
*i used 4.1 for the missing side after using the pythagorean theorem*
6: perimeter- 30.8 ft (8+5+7.8+10) area-43.5 ft [(5x7.8)/2]+[(8x6)/2]
7: p- 25.8 yd (10.8+9+6) a-27 yd [(6x9)/2]
8: p- 41.6 in (add all sides) a- 59.8 in [8x4.6]+[(10x4.6)/2]
9: p- 9 cm a-5cm [1x1]+[2x2]
10: p-48 ft [2+5+4+3+7+12+8] a-58 ft [8x2]+[3x7]+[3x7]
