a room has a length of 11 ft if the room has an area of at least 133 ft what does the width of the room have to be at least
MissTica

Area is the length times the width.

When you know the area and one of the dimensions, divide the area by the known dimension to find the other one.

133 / 11 = 12.09

The room needs to be at least 12.09 feet wide. ( round answer if needed).

Josh is hiking Glacier National Park. He has now hiked a total of 17km, and is 2km short of being 1/2 of the way done with his h
slamgirl [31]
17 + 2 = 19 km is 1/2 of the total length, that is,

19 = (1/2)h

(1/2)h = 19 multiply both sides by 2

h = 2*19

h = 38 km

The total length in kilometers is 38 km
