Ineed to find the area

plz explain how you answered

54 yd²

Step-by-step explanation:

The area of a trapezoid can be found using the formula ...

... area = (1/2)(b1 +b2)(h)

where b1 and b2 are the lengths of the parallel bases, and h is the height. Putting your numbers into the formula gives ...

... area = (1/2)(9 yd + 18 yd)(4 yd) = 54 yd²

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

150.6

all i did was i multiplied 5.02 by 30
