If it’s width is four times it’s length what is the area

Your answer is c) 400 yd^2

To get area, you multiple length and width

the length is 100

and the width is 4

4*100=400

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
