Permitted digits: 5, 6, 7, 8, 9. Even numbers must end in 6 or 8. That’s a choice of 2 digits out 5.
If no repeated digits are allowed, and the 4-digit number ends in 6, then we need to choose 3 out of the remains 4 digits. There are 4 possible choices and 6 ways of arranging each combination. So for even numbers ending in 6 there are 24 numbers with no repeated digits. Similarly there are 24 even numbers ending in 8, making a total of 48 4-digit numbers.

Answer:

  1400 square units

Step-by-step explanation:

The area can be computed by subtracting the areas of the white rectangles at three corners from the overall 60×30 rectangle.

The upper left corner white space is 10×10 = 100 square units.

The upper right and lower left white spaces are 15×10 = 150 square units each.

Then the shaded area is ...

  60×30 -100 -2(150) = 1800 -100 -300 = 1400 . . . square units

_____

<em>Alternate solution</em>

You can extend each of the horizontal edges across the figure to divide it into three rectangles. From the top down, these have dimensions and areas of ...

  35×10 +60×10 +45×10 = 10(35+60+45) = 10(140) = 1400 . . . square units

__

Area of a rectangle is the product of length and width.
