A rectangle has a perimeter of 28 units, an area of 48 square units, and sides that are either horizontal or vertical. If one ve
rtex is the point (−5, −7) and the origin is in the interior of the rectangle, find the vertex of the rectangle that is opposite (−5, −7).
1 answer:
Answer:
Opposite coordinate of (−5, −7) = (1,1)
Step-by-step explanation:
Let the sides of rectangle be a and b
Perimeter = 2 ( a+b ) = 28
a + b = 14
Area = ab = 48
The sides with sum 14 and product 48 is 8 and 6.
a = 8 and b = 6
Since origin is inside the circle, the side with 8 unit is parallel to y axis and side with 6 unit is parallel to x axis
Opposite coordinate of (−5, −7) = (−5+6, −7+8) =(1,1)
