Here are the solutions to the problems:

: Work out $102.7 \times 13$

Multiply 102.7 by 13.
$102.7 \times 13 = 1335.1$
The calculation shown in the image ( $13 \times 7 = 91$ ) is not for $102.7 \times 13$ .

The final answer is $\boxed{1335.1}$ .

: Area of a rectangular box
Identify the given dimensions.
The length of the rectangular box ( $L$ ) is 2.8 metres.
The width of the rectangular box ( $W$ ) is 2 metres.
Use the formula for the area of a rectangle.
The area ( $A$ ) of a rectangle is given by the formula:
$A = L \times W$
Substitute the given values into the formula and calculate the area.
$A = 2.8 \text{ m} \times 2 \text{ m}$ $A = 5.6 \text{ m}^2$
The final answer is $\boxed{5.6 \text{ m}^2}$ .

: Work out $0.86 \times 10.2$
Multiply 0.86 by 10.2.
$0.86 \times 10.2 = 8.772$
The final answer is $\boxed{8.772}$ .
