Q:
Match the rectangles formed by the sets of points to their corresponding areas. A(-9, 8), B(-5, 5), C(1, 13), D(-3, 16) 50 square units E(30, 20), F(39, 29), G(49, 19), H(40, 10) 300 square units I(-6, 2), J(2, 2), K(2, -8), L(-6, -8) 100 square units M(5, 5), N(11, 5), O(11, -5), P(5, -5) 80 square units Q(10, 0), R(15, 5), S(25, -5), T(20, -10) U(0, 5), V(15, 20), W(25, 10), X(10, -5)
Accepted Solution
A:
Answer:Area of ABCD = 50 square unitsArea of IJKL = 80 square unitsArea of QRST = 100 square unitsArea of UVWX = 300 square unitsStep-by-step explanation:ABCD: A (-9 , 8) , B (-5 , 5) , C (1 , 13) , D (-3 , 16)AB = β(-5 - -9)Β² + (5 - 8)Β² = 5BC = β(1 - -5)Β² + (13 - 5)Β² = 10Area = 5 Γ 10 = 50 square unitsIJKL: I (-6 , 2) , J (2 , 2) , K (2 , -8) , L (-6 , -8)IJ = 2 - -6 = 8 β horizontal line (same y-coordinates)JK = 2 - -8 = 10 β vertical line (same x-coordinates)Area = 8 Γ 10 = 80 square unitsQRST: Q (10 , 0) , R (15 , 5) , S (25 , -5) , T (20 , -10)QR = β(15 - 10)Β² + (5 - 0)Β² = 5β2RS = β(25 - 15)Β² + (-5 - 5)Β² = 10β2Area = 5β2 Γ 10β2 = 100 square unitsUVWX: U (0 , 5) , V (15 , 20) , W (25 , 10) , X (10 , -5)UV = β(15 - 0)Β² + (20 - 5)Β² = 15β2VW = β(25 - 15)Β² + (10 - 20)Β² = 10β2A = 15β2 Γ 10β2 = 300 square units
