What is the area of rectangle whose
height is 2.5 in and base is 12 in?

Step-by-step explanation:

Area of a rectangle is base times height.

A = bh

A = (12 in) (2.5 in)

A = 30 in²

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.

b) well because you get well
