Well, it is a good and interesting question

Such areas could be calculated in a single shoot and also by dividing the whole shape into other shapes and the total area would be the sum of these areas

I prefer the way of a single shoot ...

The figure represents a trapezoid:
its lower base = 21 units
its upper base = 12 units
the normal height between them = 8 units

NOW

The area of a trapezoid = [(sum of bases' lengths) ÷ 2] * height
                                       = [(12 + 21) ÷ 2] * 8 = 132 sq units


Hope that helps

1/3 cup of flour is used to make 5 dinner rolls.
Radda [10]
Divide.

1/3 / 5

Or multiply by the reciprocal of 5:

1/3 * 1/5 = 1/15

Therefore 1/15 cup of flour is used to make 1 dinner roll.

We can set up a proportion:

5/1/3 = x/5 2/3

Multiply 5 2/3 to both sides:

28 1/3 / 1/3 = x

85 = x

So 85 rolls can be made with 5 2/3 cups of flour.

A rectangle has a length of 3x-5 and a width of 2x+9.
Montano1993 [528]

Step-by-step explanation:

l = 3x - 5

w = 2x + 9

perimeter = 2l + 2w = 2(3x - 5) + 2(2x + 9) =

= 6x - 10 + 4x + 18 = 10x + 8

area = l×w = (3x - 5)(2x + 9) = 6x² + 27x - 10x - 45 =

= 6x² + 17x - 45

Find the distance between the points (7,23) and (3,-3), rounded to the hundredths place​
Molodets [167]

Answer:

26.31

Step-by-step explanation:

Use distance formula

d = \sqrt{(x_{2}-x_{1)^{2} + (y_{2}-y_ ^{1)^2} }  }

substitute in points and solve

d =  \sqrt{(7-3)^2 + (23-(-3))^{2} }

d = \sqrt{4^{2}+26^{2}  }

d = \sqrt{16 + 676}

d = \sqrt{692}

d = 26.30589288

d = 26.31 rounded
