Find the perimeter of rectangle ABCD

, with vertices A(1,7)
, B(4,7)
, C(4,−4)
, and D(1,−4)
.(1 point)
units

To find the perimeter of a rectangle, we need to add up the lengths of all four sides.

The distance formula is used to find the length of each side.

The distance between points A(1,7) and B(4,7) is 3 units.

The distance between points B(4,7) and C(4,-4) is 11 units.

The distance between points C(4,-4) and D(1,-4) is 3 units.

The distance between points D(1,-4) and A(1,7) is 11 units.

Adding up these lengths:
3 + 11 + 3 + 11 = 28 units

Therefore, the perimeter of rectangle ABCD is 28 units.
