Question

find the area of the quadrilateral field ABCD in which AB=50 m, BC=18m,CD= 82 and angel CBD=90°

Answer 1

you can use herons formula i.e.,area of triangle=
$\sqrt{s(s - a)(s - b )(s - c)}$
where s is semi perimeter

Answer 2

Answer:

Step-by-step explanation:find DB using Pythagoras theorem, then area of right triangle (1\2bh) and then area of and using herons formula and then add the areas
