  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

Alternate solution

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.

ab will be equal to

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
