Question

in parallelogram ABCD, AB=7.2cm and altitude corresponding to side AB and AD are respectively 10cm and 8cm, find AD?​

Answer 1

Answer:

Step-by-step explanation:

Thank you for asking this question. Here is your answer:

AB = 10 cm

DE = 7 cm

BF = 8 cm

Now the area of parallelogram  = base x corresponding height

AD x BF = AB x DE

AD x 7 =  10 x 8

AD = (10*7) / 8

AD = 70/8

= 8.7 cm
