Yolanda is putting up a fence for her dog in the shape of a square. Each foot of fencing costs $7. If Yolanda is planning to have each side of the fence be 10 feet long, how many feet of fencing will Yolanda need?

A square has all equal sides. 10 * 4 = ?

40

40 feet of fencing

70

i want the answer

40

To determine how many feet of fencing Yolanda will need, we need to calculate the perimeter of the square. The perimeter of any shape is the sum of all its sides.

In this case, since Yolanda wants to have each side of the fence be 10 feet long, we know that all four sides will have the same length. Therefore, to calculate the perimeter of the square, we can multiply the length of one side by 4.

Perimeter of the square = Length of one side × 4

Substituting the given length of one side, which is 10 feet, into the equation:

Perimeter of the square = 10 feet × 4

Perimeter of the square = 40 feet

Thus, Yolanda will need 40 feet of fencing.
