Use the coordinates to find the length of each side of the rectangle. Then find the perimeter.
Problem 1 :
R(1, 1), S(1,7), T(5,7), U(5,1)
Solution :
By plotting the given points on the coordinate plane, we get
From the graph,
Length of the each side of the rectangle are
AB = 4 units, BC = 6 units, CD = 4 units, and AD = 6 units
Perimeter of the rectangle = sum of all its four sides
= AB + BC + CD + AD
= 4 + 6 + 4 + 6
= 20 units
Problem 2 :
E(3, 6), F(7, 6), G(7, 2), H(3, 2)
Solution :
By plotting the given points on the coordinate plane, we get
From the graph,
Length of the each side of the rectangle are
AB = 4 units, BC = 4 units, CD = 4 units, and AD = 4 units
Perimeter of the rectangle = sum of all its four sides
= AB + BC + CD + AD
= 4 + 4 + 4 + 4
= 16 units
Problem 3 :
E(1, 7), F(3, 7), G(3, 4), H(1, 4)
Solution :
By plotting the given points on the coordinate plane, we get
From the graph,
Length of the each side of the rectangle are
AB = 2 units, BC = 3 units, CD = 2 units, and AD = 3 units
Perimeter of the rectangle = sum of all its four sides
= AB + BC + CD + AD
= 2 + 3 + 2 + 3
= 10 units
Problem 4 :
W(2, 7), X(2, 0), Y(6, 0), Z(6, 7)
Solution :
By plotting the given points on the coordinate plane, we get
From the graph,
Length of the each side of the rectangle are
AB = 4 units, BC = 7 units, CD = 4 units, and AD = 7 units
Perimeter of the rectangle = sum of all its four sides
= AB + BC + CD + AD
= 4 + 7 + 4 + 7
= 22 units
