Find the areas of the trapezoids. need in 10 minutes. will give 20 points! 6th-grade ! this is a test!

answer and step by step explanation:

identifying the area of trapezoid?

step 1: identify the length of both bases. the bases are parallel sides

step 2: add the lengths to the bases. for   8 cm and 13

step 3: identify the height of the trapezoid

step 4: multiply the sum of the lengths of the bases by the

step 5: divide the result by 2

answer:

the formula for area of a trapezoid is (base 1 * base 2) divided by 2, times the height

step-by-step explanation:

base 1 = top or bottom length

base 2 = the other base length

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 %
