Question

in parallelogram abcd if ab=8cm and the altitudes corresponding ab and ad are dm=6cm and bn=12cm respectively, determine AD.​

Answer 1

Answer:

base=4

Step-by-step explanation:

1/2×d1×d2(area of parallelogram)

1/2×6×12=48

(area of parallelogram)=base ×height

=AD×12=48

=AD=48÷12

AD=4

THEREFORE BASE =AD=4cm

Answer 2

We know that, Area of a parallelogram = Base × Corresponding altitude ∴ Area of parallelogram ABCD = AD × BN = AB × DM ⇒ AD × 5 = 8 × 4 ⇒ AD = 8× 4/58 = 6.4 cm
