11. pt = 8cm ,qt= 5cm di persegi itu ada segitiga siku siku maka buat nentuin pq pakai rumus (akar (8cm pangkat 2) – (5cm pangkat 2)) = 7 cm persegi, pqrs = sxs = 7×7 = 49

14. diket : a = 10 b = 22
sisi miring = 10 t = ?
x^2 = 10^2-6^2
x^2 = 100-36
x^2 = 64
x = 8^2
luas = 1/2x(a+b)xt
= 1/2x(10+22)x8
= 1/2x32x8
= 32×4
= 128
