A ≈ 153.1 units²

Step-by-step explanation:

area (A) of rectangle is

A = length × breadth = 16 × 8 = 128 units²

The diameter of the circle is 8 , then radius = 8 ÷ 2 = 4

area of semicircle = × πr² ( r is the radius )

                              = × π × 4²

                             = × π × 16

                             = 8π

Then area of figure = 128 + 8π ≈ 153.1 units² ( to the nearest tenth )

I hope it helps you !!..✌️

sure i'm up for it

step-by-step explanation:

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 %
