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.
