A rectangular cardboard has dimensions as shown. The length of the cardboard can be found by dividing its area by its width. What is the length of the cardboard in inches?

The length of the cardboard in inches is inches

Step-by-step explanation:

The remaining part of the question which is an image is attached below.

Step-by-step explanation:

The area of a rectangle is given by

Area = Length × Width

Hence, to determine the length of the rectangular cardboard, we can write that

Length = Area/Width

That is dividing its area by its width (just as stated in the question)

Now, in the diagram shown in the attachment

Area = square inches = square inches

width = inches = inches

Since, the length is given by

Then,

∴ inches

Hence, the length of the cardboard in inches is inches

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
