Question

A park in the shape of quadrilateral ABCD has angle C equals to 90 degree ab=18m BC = 24m CD = 10m and AD=16m how much area it occupy?​

Answer 1

the shape is quadrilateral.....

Answer 2

Calculate area of ΔBCD = 1/2 x 24 x 10 = 120.

Apply pythogoras theorem to get the diagonal.

Therefore BD=26

Use herons formula because you have 3 sides.

Hence ΔABD=142(approx)

Therefore the total area is 120+142=262.
