You can use Heron Formula in the calculator to output the result, but i still show you the steps on paper thro
lengths of the 3 lines: \sqrt{392} , \sqrt{676} , \sqrt{676}
s= (\sqrt{392} + \sqrt{676} + \sqrt{676})/2=35.89949494
area= \sqrt{s(s- \sqrt{392} )(s- \sqrt{676})^2 } =238
Answer:
The expression representing the width is 3+2L
The width is 9ft
Step-by-step explanation:
Area of a rectangle = Length×width
A = L × W...(1)
Let the length be represented as L
Since the width of the rectangle is 3feet longer than two times its length, this is expressed as:
First, width is twice as long as the length i.e W = 2L
If the resulting width is now 3 feet longer, the final width of the rectangle will be expressed as:
W = 3+2L...(2)
Area (A) = 27ft
Substituting equation 2 into 1, we have;
A = L(3+2L)
A = 3L+2L²
27 = 3L+2L²
2L²+3L-27 = 0
Factorizing the resulting equation
(2L²+9L)-(6L-27) = 0
L(2L+9)-3(2L+9) = 0
L-3 = 0 and 2L+9 = 0
L = 3 and L = -9/2
Disregarding the negative value and substituting L = 3 into equation 2 to get the width
W = 3+2(3)
W = 3+6
W = 9ft
Answer:
Scalene triangle as there are no sides given.
or,
Measure it using a ruler and classify it based on the result.
Step-by-step explanation:
Scalene triangle = No sides are equal.
Isosceles triangle = 2 sides equal.
Equilateral triangle = All sides equal.
Right angled triangle = One angle is 90.
Since, the picture hasn't given any sides, i am gonna say it's a scalene triangle.
If, the triangle is for measure, measure it using a ruler and classify it based on the result.
Answer:
36%
Step-by-step explanation:
Red and blue is 8%
and= multiply
0.08 unmultiply = 0.64 or 64%
yellow = 100-64= 36%
The answer is eighty/ eighty-two
