Question

A
15 cm
B
In the figure, AB and DC are parallel sides of a trapez
are parallel sides of a trapezium ABCD
and ZADC=90°. Given, AB = 15 cm, CD = 40 cm and diagonal
AC = 41 cm, calculate the area of trapezium ABCD.
41 cm
40 cm
Fig. Q. 13
[Hint. In AADC, AD = VAC? - DC? = V412 – 402 = 9 cm
Now, Area of trap. ABCD = = X AD (AB + DC)]​

Answer 1

40" (and any subsequent words) was ignored because we limit queries to 32 words.
