Laura framed her rectangular garden with boards. She used 1 board on each side. The longer sides

were 7.5 feet long, and the shorter sides were 6.5 feet long. What is the area of her garden in square

feet?

A) 14

B) 28

C) 42.25

D) 48.75

D) 48.75

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Area of a rectangle: length x width

Replacing with the values given and solving for A (area)

A= 7.5 ft x 6.5 ft =48.75 ft2

The area of the garden in square feet is 48.75. (option D).

Feel free to ask for more if needed or if you did not understand something.  

addition

step-by-step explanation:

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
