Question

АВСD is a trapezum with AB|| CD and LABC -90 and neight BC= 4m ar (AOB) - Ar(COD) = 6 m² Find AD ​

Answer 1

Answer:

6cm,8cm and 10cm has to be determined.

This is a right triangle with perpendicular sides of length 6 and 8cm.

The area can be derived using Heron's theorem.

The area is given by

s.(s−a).(s−b).(s−c)

where s is semi perimeter equal to

2

6+8+10

=12

a=6,b=8 and c=10.

The area of the triangle is equal to

12.6.4.2

=

576

=24cm

2

Hence, the answer is 24 cm
