Question

A’Leila is building a pen for her pet donkey. The pen is a rectangle with one side measuring b yards and the adjacent side measuring a yards. A’Leila knows that . a. Write two different expressions giving the perimeter of the donkey’s pen.

Answer 1

c. Explain why you used that expression to evaluate the perimeter of the donkey’s pen

Answer 2

can you make this short and sould like a 7th grader

Answer 3

The first expression for the perimeter of the donkey's pen would be: P = 2a + 2b

The second expression for the perimeter of the donkey's pen would be: P = a + a + b + b = 2a + 2b (which is the same as the first expression).

Answer 4

I used the expression P = 2a + 2b to evaluate the perimeter of the donkey's pen because a rectangle has four sides, and the perimeter is the sum of the lengths of all four sides. In this case, we have two sides of length a and two sides of length b.

To find the total length of all four sides, we multiply the length of each side by 2 and then add them together. So, we have 2a + 2b. This expression accounts for both the length of the sides measuring a yards and the length of the sides measuring b yards, giving us the total perimeter of the pen.

Answer 5

Sure! The perimeter is the distance around the edges of a shape. For the donkey's pen, we need to add up the lengths of all four sides. Since the pen is a rectangle, it has two sides that are a yards long and two sides that are b yards long. To find the perimeter, we multiply each side length by 2 and then add them together. So, the expression for the perimeter is 2a + 2b.
