Aroom has an area of 121 ft2 but carpeting is only sold in m2. how much carpeting is needed to carpet the room

11.24 sq. m

Step-by-step explanation:

Note that 1 ft = 0.3048 m.

The area of a room is and this area needs to be covered with carpet.

Then 11 ft = 3.3528 m

and

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.
