Question

in a parallelogram ABCD the length of the altitude corresponding to AB is 8cm what is the length of the altitude corresponding

Answer 1

Heya !!!


here is your answer !!

area of ll gm = base * height



=> AB * DM


=> 20 cm * 8cm


=> 160 cm² .


now ,



AREA of ll gm => base * height


=> AD * DN


=> 160 cm² = 10cm * DN


DN = 16 cm




hence ,the length of crossponding altitude is


16 cm



hope it helps you dear !!!

thanks !!

Answer 2

area of a Parallelogram is equal to
Ar= (1/2) x (sum of The parallel sides) x (distance between the parallel sides)

So,
(1/2)x(20+20)x(8) = (1/2)x(10+10)x(a)
a= 16cm

done
