Will award brainliest to whoever answers both parts a farmer has a field in the shape of a trapezoid, formed by three congruent isosceles triangles, as shown below. he wants to plant vegetation in the green shaded area and pour concrete in the remaining area. 1. what area of the field does the farmer plan to use for vegetation planting? round your answer to the nearest tenth of a square yard. 2. if a bag of top soil costs $12 and covers 36 square yards, how much will it cost the farmer to cover the vegetation part of his field with the top soil?

check the picture below.

now, we're assuming the trapezoid is an isosceles trapezoid, namely AD = BC, and therefore the triangles are twins.

incidentally, b is the height of the trapezoid and likewise is also the altitude or height of the concrete triangle.

so we can simply get the area o the trapezoid, notice the bottom base is a+185+a, and then get the area of the concrete triangle and subtract the triangle from the trapezoid, what's leftover is just the vegetation area.

so that's the area of the trapezoid, now let's get the area of the triangle.

since we know 36 yd² cost 12 bucks, then how much will it be for 39475.018 yd²?

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
