A rectangular sign has length of 3 and 1/2 ft and a width of 1 and 1/8 ft. Will the area of the sign be greater or less than 3 and 1/2 square ft? How do you know? What is the area of the sign?

Area is greater than sq ft.

Step-by-step explanation:

Length of rectangular sign board = ft

Width of rectangular sign board = ft

Area of a rectangle is given by the formula:

To find the area, we are going to multiply with .

is greater than 1.

Therefore the multiplication will be greater than .

Hence, we can say that area will be greater than sq ft.

Area of the sign:

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
