Question

In the given figure, ABCD is a trapezium in which
AD = 13 cm, BC = 5 cm, CD = 17 cm and
ZA = B = 90°
Calculate : (i) AB (ii) Area of trap. ABCD.​

Answer 1

Answer:

(I) 3

Step-by-step explanation:

(I) let us contract a line parallel to AB passing through the vertex B and name it BE....we get a right angled triangle BEC....in the triangle we know that BC=5cm and CE= CD- AB= 17-13= 4 cm...hence by Pythagoras theorem we get AB as 3 cm
