Answer:
40 in is the perimeter of the rectangle.
Step-by-step explanation:
P = 2L + 2W.
Here we have P = 2(2)(6 2/3 in) + 2(6 2/3 in) = 6(6 2/3 in) = 40 in
White roses - 5 30 40 50
Pink roses - 7 42 56 70
To solve, take the pink rose amount, divide by 7 to get the times given pink roses. Multiple it by 5 to get the amount of white roses.
For the last one, divide by 5 to get the amount of times given white roses. That’s ten times. Multiple it by 7, as that’s 10 times you get 7 pink roses, answer is 70.
36/3.14 gives us approximately 11.465
Answer:
length = 11 yard
width = 5 yard
Step-by-step explanation:
Area of a rectangle = L W
where A = 55 yard
L = 3W - 4
find: Length
width
solution:
A = L W
55 = (3W - 4) W
55 = 3W² - 4W
3W² - 4W - 55 = 0
use quadratic equation to solve for W:
W = <u> - (-4) ± √(-4)² - 4(3)-55 </u>
2(3)
W = 5, W = -11/3
substitute W=5 to equation L = 3W - 4 to solve for L
L = 3W - 4
L = 3(5) - 4
L = 15 - 4
L = 11
therefore, the dimensions of a rectangle:
length = 11 yard
width = 5 yard
