Question

if parallelogram ABCD and triangle ABC have a common base between the same parallels and area ABC equal to 45 CM square find area of a b c d

Answer 1

when parallelogram and triangle on same base and between same parallel the area of triangle is half of the area of parallelogram
area (∆ABC) = 1/2 area (|| gm ABCD)
45 = 1/2 area (|| ABCD)
AREA ( || ABCD) = 90 sq . cm
