Question

solve this plz I have exam tomorrow

Answer 1

area= b.h
if b = 2h then
512 = 2h.h
256= 2h²
16=h

height is 16
base is 32

Answer 2

let the height be x and then the length will 2x

area of parallelogram = height * base


here, area of parallelogram = x *2x 

512= x*2x

512 = 2x^2

512/2 = x^2

256 = x^2

16 = x

then

base of parallelogram = x  = 16cm

and length of parallelogram = 2x =2*16 = 32cm


i hope this will help you
