Find the area of a rhombus whose diagonals are 4.

Given:

d1 (First diagonal) = 4

d2 (second diagonal) = 4

Find: S (area)

Decision:

To solve this problem, we need to use one of the formulas for finding the area of a rhombus. Since we only know the diagonals, we should take a formula with diagonals. The area is equal to half the product of the diagonals.

S = 0.5 * d1 * d2

Let’s plug the data into the formula.

S = 0.5 * 4 * 4

S = 0.5 * 16

S = 8

We found the area of the rhombus. Now we can write down the answer.

Answer: The area of the rhombus is 8.S = 8.
