Area = 300 square feet
length must be 12 feet longer than width
find the dimension of the pen

feet

feet

Step-by-step explanation:

Let x be the width of a rectangle

Let l be the length of a rectangle

Let A be the area of rectangle

Given.

Length must be 12 feet longer than width

therefore

Area of rectangle

We know that area of rectangle is

---------------------(1)

put all known values in equation 1

Find roots by this formula

check both value in equation 1

for

is satisfy the equation

So The length of rectangle =24.32 feet

And width is 12.32 feet

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

b. x- 48 =120
