Answer:
10 units
Step-by-step explanation:
You want the perimeter of the rectangle with vertex coordinates E(1,7), F(3,7), G(3,4) , and H(1,4).
The lengths of the sides can be found by counting grid squares or subtracting coordinate values.
The distance between E and F, for example is 3 - 1 = 2 units on the horizontal line y = 7.
Similarly, the distance between F and G is 7 - 4 = 3 units on the vertical line x = 3.
Opposite sides of the rectangle are the same length. The perimeter is the sum of side lengths, so will be ...
P = 2(L +W) = 2(3 +2) = 10 . . . . units
The perimeter of the rectangle is 10 units.
