Scientific notation says, "leave only one guy to the left of the decimal point", so... 25.8 needs to turn to 2.58 then... multiplied by some power of 10, we just need to move the dot over one spot, so 10 at the 1 power,  \bf 2.58\times 10^1\implies 2.58\times 10

Answer ---> 2.58*10^1

So, when you write 10^n, you have to move the comma n times.

So you move the comma 1 time from 2.58 (moved the comma 1 time on the left) to the right and get 25.8

The area of the given trapezoid will be the sum of the areas of the triangular part and the rectangular part.

Now, the area of the rectangle, A_1 is:

A_1=length \times width=2\times 1.5=3 squared yards

Likewise, the area, A_2 of the triangle will be:

A_2=\frac{1}{2}\times base\times height=\frac{1}{2}\times 5\times 1.5=3.75 yd^2

Thus, the area of the trapezoid=A_1+A_2=3+3.75=6.75 yd^2

Thus the first option is the correct option.
