Mathematics and Science Q34
- Option : A
- Explanation :
Given, BD = 40 cm, AM =16 cm , NC=12cm
∴ Here, BD divides quadrilateral in two triangles.
Now,
Area of ΔABD = 1/2 x BD xAM
1/2 x 40 x 16 =320 cm∧2.
∴ Area of ΔBCD = 1/2 x BD x NC
=1/2 x40 x12=240 cm∧2
Area of quadrilateral
ABCD = 320 + 240 = 560 cm∧2
