area of special quadrilaterals practice Unit 6 lesson 4

Answer 1

1. Find the area of a rhombus with diagonals of length 10 cm and 12 cm.
Area = (d1 * d2) / 2
Area = (10 * 12) / 2
Area = 60 cm^2

2. Find the area of a parallelogram with base 8 cm and height 6 cm.
Area = base * height
Area = 8 * 6
Area = 48 cm^2

3. Find the area of a trapezoid with bases of length 5 cm and 7 cm, and height of 4 cm.
Area = (base1 + base2) * height / 2
Area = (5 + 7) * 4 / 2
Area = 24 cm^2

4. Find the area of a kite with diagonals of length 10 cm and 12 cm.
Area = (d1 * d2) / 2
Area = (10 * 12) / 2
Area = 60 cm^2

5. Find the area of a square with side length 6 cm.
Area = side^2
Area = 6^2
Area = 36 cm^2

6. Find the area of a rectangle with length 10 cm and width 4 cm.
Area = length * width
Area = 10 * 4
Area = 40 cm^2

7. Find the area of a quadrilateral with side lengths of 5 cm, 7 cm, 9 cm, and 8 cm (in that order).
This shape is not a special quadrilateral, so we cannot find the area without additional information about the angles or diagonal lengths.
