To determine which multiplication problem correctly represents the total area of the figure, we need to know the dimensions of the rectangle. Area of a rectangle is found by multiplying its length and width.

If we have a rectangle with:

• Length (L) and Width (W), the area $A$ is calculated by: $A = L \times W$

Let's analyze the options:

• Option A: $1 \times 21 = 21$ suggests a rectangle with one side of length 1 and the other of length 21. This gives an area of 21 square units.
• Option B: $4 \times 6 = 24$ suggests a rectangle with dimensions 4 and 6, giving an area of 24 square units.
• Option C: $4 \times 5 = 20$ suggests a rectangle with dimensions 4 and 5, giving an area of 20 square units.
• Option D: $7 \times 3 = 21$ suggests a rectangle with dimensions 7 and 3, giving an area of 21 square units.

Without seeing the actual figure, it's impossible to definitively say which multiplication problem is correct, but the pattern follows that the area is determined by multiplying the two sides of the rectangle.
