To find the perimeter of rectangle ABCD, we calculate the distance between each pair of points and sum them up.
AB: √((4-1)^2 + (7-7)^2) = √3^2 = 3 units
BC: √((4-4)^2 + (-4-7)^2) = √0^2 + 11^2 = 11 units
CD: √((1-1)^2 + (-4-7)^2) = √0^2 + 11^2 = 11 units
DA: √((1-4)^2 + (7-7)^2) = √3^2 = 3 units
Perimeter = 3 + 11 + 11 + 3 = 28 units
Therefore, the perimeter of rectangle ABCD is 28 units.
Question 2:
Using the same approach as question 1:
Perimeter = 32 units
Therefore, the perimeter of rectangle ABCD with vertices A(−8,3), B(−1,3), C(−1,−6), and D(−8,−6) is 32 units.
Question 3:
Perimeter = 16 units
Therefore, the perimeter of rectangle LMNO with vertices L(−2,−1), M(−5,−1), N(−5,−6), and O(−2,−6) is 16 units.
Question 4:
Perimeter = 16 yards
Therefore, the park needs 16 yards of fencing for the playground.
Question 5:
Perimeter = 40 feet
Therefore, the restaurant will need 40 feet of wall material to build the new outside seating area.
