The subtraction represents the length of one leg, so the answer is A
Let x = first number, and y = second number.
x + y = 40 (1)
x - y = 6.5 (2)
Rearrange (2)
y = x - 6.5 (3)
Sub (3) in (1)
x + (x - 6.5) = 40
2x - 6.5 = 40
2x = 33.5
x = 16.75 (4)
Sub (4) in (1)
16.75 + y =40
y = 23.25
x * y = 16.75 * 13.25 = 221.9375
The product is 221.9375

When 10 is to a negative power, you move the decimal to the left because the number is less than positive 1. Here 10 is to the power of -7, so you move the decimal (which is after/behind 5) to the left 7 times.
