abcd is trapezium bc is 17 ab is 16 dc is 8 find area of abcd

Answer 1

ABCD can be drawn with a right angle at A. Then, if you drop an altitude from CD to AB, it will divide AB into two equal parts of length 8.

Now on the right side you have a right triangle, with base=8 and hypotenuse=17. Now you can figure the height h, and so the area is

h * (8+16)/2
