Calculate the area of the irregular polygon shown below:

26 in²

Step-by-step explanation:

If we consider the outside rectangle, then subtract the 2 congruent white rectangles.

Area of outside rectangle = 10 × 5 = 50 in²

Area of 2 white rectangles = 2 × 4 × 3 = 24 in²

Thus the area of the E shape = 50 - 24 = 26 in²

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 %
