Cynthia Besch wants to buy a rug for a room that is 29 ft wide and 30 ft long. She wants to leave a uniform strip of floor around the rug. She can afford to buy 756 square feet of carpeting. What dimension should the rug have?

Dimensions of rug:

Length = 28 ft

Width =  27 ft

Step-by-step explanation:

The given dimensions of the room is:

Length = 30 ft

Width = 29 ft

Area of carpeting = 756 sq ft

Kindly refer to the attached image.

Let the uniform strip around floor is of length = ft

This feet will be 2 times along the length and

2 times along the width of room.

So, length of rug = 30 -2 and

Width of rug = 29 -2

It will be rectangular in shape.

Area of a rectangle is given as:

Negative length not possible.

So,Length of strip,  

Dimensions of rug:

Length = 30 -2 = 28 ft

Width = 29 -2 = 27 ft

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
