Read each question carefully and calculate the area of the rhombus. Show your work.

Recall: The area of a rhombus is given by the formula A = (1/2) * d1 * d2, where d1 and d2 are the lengths of the diagonals.

1. A rhombus has diagonals measuring 10 cm and 12 cm. What is its area?

10 cm12 cm

2. The diagonals of a rhombus are 8 inches and 15 inches. Find the area.

3. If a rhombus has an area of 48 square meters and one diagonal is 6 meters, the other diagonal is   meters.

4. A rhombus with diagonals of 7 cm and 4 cm has an area of   square centimeters.

5. Which of the following is the correct formula for the area of a rhombus?

a

A = s²

b

A = lw

c

A = (1/2)d₁d₂

d

A = bh

6. The diagonals of a rhombus are always equal in length.

T

True

F

False

7. A rhombus has a perimeter of 40 cm. If one of its diagonals is 16 cm, find the area of the rhombus. (Hint: Use the Pythagorean theorem to find the other diagonal.)
