Question

Abcd is a parallelogram AE is perpendicular to DC and CF is perpendicular to AD.if AB = 12cm,AE=7cm and CF =10cm.Find AD

Answer 1

Area of parallelogram = Base* height
from the given fig
= AD*CF= CD*AE
=AD*10 = 16*8 // ABCD is a parallelogram //

AB = CD = 16 cm

AD = (16*8) /10
= 12.8 cm
