Parallelogram Practice Problems

15 parallelogram problems with full worked solutions, graded from warm-up to stretch — plus an unlimited supply you can generate yourself. Every answer is computed by the same verified function that powers the parallelogram explorer, so the solutions cannot disagree with the formulas. Free, no account, nothing to install.

Formulas you need

  • Area: A=bhA = b h
  • Perimeter: P=2(a+b)P = 2(a + b)

where b = base, h = height (perpendicular to base), a = slanted side, A = area

Warm-up

  1. A parallelogram has base b = 3 and height h = 1. Find the area (A).

    Answer & working

    3 units²

    A = b · h = 3 · 1 = 3

  2. A parallelogram has base b = 5 and slanted side a = 4. Find the perimeter (P).

    Answer & working

    18 units

    P = 2(a + b) = 2(4 + 5) = 18

  3. A parallelogram has base b = 2 and height h = 1. Find the area (A).

    Answer & working

    2 units²

    A = b · h = 2 · 1 = 2

  4. A parallelogram has base b = 1 and slanted side a = 2. Find the perimeter (P).

    Answer & working

    6 units

    P = 2(a + b) = 2(2 + 1) = 6

  5. A parallelogram has base b = 4 and height h = 2. Find the area (A).

    Answer & working

    8 units²

    A = b · h = 4 · 2 = 8

Core practice

  1. A parallelogram has base b = 3 and height h = 4. Find the area (A).

    Answer & working

    12 units²

    A = b · h = 3 · 4 = 12

  2. A parallelogram has base b = 7 and slanted side a = 9. Find the perimeter (P).

    Answer & working

    32 units

    P = 2(a + b) = 2(9 + 7) = 32

  3. A parallelogram has base b = 6 and height h = 4. Find the area (A).

    Answer & working

    24 units²

    A = b · h = 6 · 4 = 24

  4. A parallelogram has base b = 9 and slanted side a = 6. Find the perimeter (P).

    Answer & working

    30 units

    P = 2(a + b) = 2(6 + 9) = 30

  5. A parallelogram has base b = 10 and height h = 4. Find the area (A).

    Answer & working

    40 units²

    A = b · h = 10 · 4 = 40

Stretch

  1. A parallelogram has base b = 6.5 and height h = 4.5. Find the area (A).

    Answer & working

    29.25 units²

    A = b · h = 6.5 · 4.5 = 29.25

  2. A parallelogram has base b = 8.5 and slanted side a = 10. Find the perimeter (P).

    Answer & working

    37 units

    P = 2(a + b) = 2(10 + 8.5) = 37

  3. A parallelogram has base b = 3.5 and height h = 1.5. Find the area (A).

    Answer & working

    5.25 units²

    A = b · h = 3.5 · 1.5 = 5.25

  4. A parallelogram has base b = 3.5 and slanted side a = 10. Find the perimeter (P).

    Answer & working

    27 units

    P = 2(a + b) = 2(10 + 3.5) = 27

  5. A parallelogram has base b = 2.5 and height h = 5.5. Find the area (A).

    Answer & working

    13.75 units²

    A = b · h = 2.5 · 5.5 = 13.75
