Hey! My little sister is having trouble, and I'm not sure what to do. She tried asking our parents, but they didn't learn the way she's learning now, and neither did I. So here we are. Here's the question: Find the area of a rectangle that has a length of 7 feet and a width of 4/5 feet

I got you!

your answer is 5.6 feet^2

I hope i helped

area = length x width

so you do 7 x 4/5 = 5.6feet^2

(when you multiply fraction, you multiply top by top and bottom by bottom.

so it becomes (7x4)/5 = 28/5 = 5.6)

Hope that answers your question

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
