Area = b*h let h be height of original, that makes the base 8h (8 times the base) Let h * 8h=A for area of original parallelogram 8h^2=A The 2nd parallelogram the height is 2h and the base is 16h (doubled) and the area is 384 more than the original area so 2h*16h=A+384 32h^2 = A+384 32h^2-384=A Substitute 8h^2 from the first formula for A in the second formula 32h^2-384=8h^2 24h^2=384 h^2=384/24 h^2=16 h=4 original height is 4 which makes the base 32
