the rectangle has an area of 24 square centimeters. find the length a of the rectangle.


the length of the rectangle is a and the width of the rectangle is a - 5

For this case we have that by definition, the area of a rectangle is given by:

Where:

a: It is the length of the rectangle

b: It is the width of the rectangle

We have as data:

So:

We look for two numbers that when multiplied get -24 and when added get -5.

These numbers are -8 and 3:

Thus, the solutions are:

We choose the positive value, so the length of the rectangle is A = 8

8 centimeters

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
