Question

If the perimeter of a parallelogram ABCD is 36cm and AD=8cm, what is the length of AB?​

Answer 1

Answer:

Step-by-step explanation:

There will be two right angled triangle namely triangle ADL and triangle ABM.

You can prove that the two triangle are similar to each other by using the properties, after that with the help of similarities, AL is in proportion to AM as AD is to AB

AL/AM = AD/AB

12/18 = 6.4/x

12 x = 18 * 6.4

12 x = 115.2

X = 115.2/12

X = 9.6 cm
