In a rectangular coordinate system, what is the area of a rhombus whose vertices have the coordinates (0, 3.5), (7, 0), (0, -3.5), (-7, 0)?
Answer/Solution
49
Steps/Work
Area of rhombus= 1/2* D1 *D2
Length of 1st diagonal = 7+7= 14
Length of 2nd diagonal= 3.5+3.5= 7
Area= 1/2*14*7= 49
D is the answer
Length of 1st diagonal = 7+7= 14
Length of 2nd diagonal= 3.5+3.5= 7
Area= 1/2*14*7= 49
D is the answer
