For a right angle triangle, Hypotenuse^2 = base ^2 + Height^2

12. Other leg of right angle triangle = (15^2 – 12^2)^0.5 = 9

Area = ½ * 9* 12 = 54 in^2

Perimeter = 15+12+9 = 36m

14. Other leg of right angle triangle = (85^2 – 84^2)^0.5 = 13

Area = ½ * 13* 84 = 546 m^2

Perimeter = 85+84+13 = 183 m

16. Area = ½ * Base * Height

36 = ½ * 12 * x

X = 6 in

18. Area = base * height

476 cm^2 = x * 17 cm^2

X = 476/17 cm = 28 cm
