Question

In the figure, diagonal BD is 40 m long
and perpendiculars to it from the
opposite vertices are 8 m and 10 m
respectively. Find area of quad ABCD.​

Answer 1

Answer:

Step-by-step explanation:

In triangle ADB

Area = 1/2 * b*h

= 1/2 * 40 * 10

= 200 m^2

In triangle DCB

Area = 1/2 * b * h

= 1/2 * 40 * 8

= 160 m^2

So area of the quadrilateral = area of triangle ADB + area of triangle DCB

= 200 + 160 = 360 m^2
