Question

In the below figure, ABCD is a
Parallelogram, AE perpendicular to DC, CF perpendicular to AD.
If AB =16cm, AE=8cm and CF=10cm, find AD.​

Answer 1

Step-by-step explanation:

area of given parallelogram = base × height (16×8)= 128

Now,

Let AD base and CF be height

according to question

area of parallelogram = AD×CF

128. = AD × 10

AD. = 128/10

AD. = 12.8

Answer 2

Answer:

ABxAE=ADXCF

16X8=ADx10

128=ADx10

AD=128/10

AD =12.8
