Question

calculate the area of a quadrilateral ABCD when length of the diagonal AC equal to 15 cm and the length of perpendicular from B and D on ACB 8 cm and 10 cm respectively​

Answer 1

Step-by-step explanation:

I am assuming that the diagonal of 10 divides the quadrilateral into two triangles

One triangle apex is a and the other apex is b

Then, assuming that the prependicular from a to the diagonal is 5

And the perpendicular from b to the same diagonal is 6.

The task then is to calculate the area of both triangles separately then sum the two areas.

1/2 x 10 x 5 = Area 1

1/2 x 10 x 6 =Area 2

Area 1 + Area 2 = 55 sq units
