Answer 1

8*5=40 (дм2)-площадь участка

Answer 2

Calculation of the Area of the Ant's Plot

To calculate the area of the ant's plot, we need to multiply the lengths of its sides. The given dimensions are 8 dm and 5 dm. Therefore, the area of the ant's plot is:

Area = Length × Width = 8 dm × 5 dm = 40 dm².

Calculation of the Length of the Fence

To calculate the length of the fence that the ant needs to build around its plot, we need to add up the lengths of all four sides. Since the plot is rectangular, opposite sides have the same length.

The length of the fence can be calculated using the formula:

Length of Fence = 2 × (Length + Width) = 2 × (8 dm + 5 dm) = 2 × 13 dm = 26 dm.

Therefore, the ant needs to build a fence with a length of 26 dm around its plot.
