A. sudut MSP = 180-90-45 = 45 derajat
b. panjang MN = SR = 26
c. Panjang PM, QN = 48-26 = 22:2 = 11cm, t = 26cm
d. Luas = (a+b)t :2 = 962 cm2

1. MSP = 45°, RNQ = 90°
2. MN = SR = 26 cm
3. PM = QN = 11 cm (48 - 26 / 2 = 22 / 2) , t = SR = 26 cm
4. Luas PQRS =  \frac{a+b}{2}  t
 \frac{(26+48)}{2} 26
 \frac{74}{2} 26
= 962 cm²
