Answer:
Step-by-step explanation:
The diagonals of the given parallelogram are QS and RT. We would first determine if its diagonals are congruent.
QS = √(1 - 5)² + (3 - 3)² = 16
RT = √(3 - 3)² + (4 - 2)² = 4
Since QS ≠ RT, it means that they are not congruent and this means that the parallelogram is not a rectangle.
Let us check if the diagonals are perpendicular.
Slope of QS = (3 - 3)/(5 - 1) = 0/4
Slope of RT = (2 - 4)/(3 - 3) = - 2/0
The slopes are not opposite reciprocals. It means that the diagonals are not perpendicular. Therefore, the correct option is
D. QRST is none of these because its diagonals are neither congruent nor perpendicular.
Answer:
The larges perimeter she can make becomes is 96 ft
Step-by-step explanation:
Here we note that the available brick is 47 ft²
Therefore, she has 47 square cement blocks
Let the length of the sides of the rectangle with the most perimeter be x and y
Then 2·x + 2·y = 47 which is not possible because 47 is a prime number
Hence we have the possible sides of the rectangle is a single line of square blocks such that
x × y = 47 ft² where y = 1 hence x = 47
The larges perimeter she can make becomes, 2 × (1 + 47) = 96 ft.
