A rectangular field has a perimeter of 100 feet. Its length is 20 feet longer than its width. What are the dimensions of the field?
O A. 15 feet by 35 feet
O B. 20 feet by 30 feet
O c. 35 feet by 55 feet
O
D. 40 feet by 60 feet

A. 15 feet by 35.

Step-by-step explanation:

According to this word problem, the rectangular field has a perimeter of 100 feet.

The formula for perimeter of a rectangle is side + side + side + side.

A rectangle has two pairs of equal sides and four sides.

So, the equation to represent the perimeter would be:

15 + 35 + 15 + 35 = 100.

Now, we must answer the second part of the question.

"The length is 20 feet longer than its width."

The width is 15.

15 + 20 = 35.

35 is twenty feet longer than 15.

Therefore, the dimensions of the field are 15 feet by 35 feet.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
