Answer:

|SU|=\sqrt{13}

Step-by-step explanation:

The given parallelogram has vertices R(1, -1), S(6, 1), T(8, 5), and U(3, 3) .

Recall the distance formula;

We use the distance formula to determine the length of the diagonals.

For diagonal R(1,-1) and T(8,5), We have;

|RT|=\sqrt{(8-1)^2+(5--1)^2}

|RT|=\sqrt{(7)^2+(6)^2}

|RT|=\sqrt{49+36}

|RT|=\sqrt{85}

For the diagonal S(6,1) U(3,3)

|SU|=\sqrt{(6-3)^2+(5-3)^2}

|SU|=\sqrt{(3)^2+(2)^2}

|SU|=\sqrt{9+4}

|SU|=\sqrt{13}

Therefore the shorter diagonal is:

|SU|=\sqrt{13}

The perimeter of a rectangle is 132 feet and its area is 1080 square feet. find the dimensions
FrozenT [24]
2x + 2y=132

xy=1080

Let x=1080/y

2160/y + 2y=132
2y^2 - 132y +2160=0
2(y^2-66y+1080)=0
2(y-30)(y-33)=0
y=30 or y=33
(36,30) or (30,36)

So... x=30,36 and y=36,30. Either way, the answer is 30 by 36 or 36 by 30.
