Answer:

A=82 meters^2

Step-by-step explanation:

First we will split the shape into two rectangles.

Now that it is in two separate peaces, solve each one individually

Remember   A = l*w

10*5=50

8*4=32

Finally add the two areas together

50+32=82

Answer:

82

Step-by-step explanation:

<u>Vertical rectangle:</u>

A = bh

A = (5)(10)

A = 50

<u>Horizontal rectangle:</u>

h = 10 - (3 + 3)

h = 4

A = bh

A = (8)(4)

A = 32

<u>Combined:</u>

50 + 32

82

Trapezoid DEFG is dilated by scale factor of 2\3 to form trapezoid D'E'FG. Side E'F' measures 32. What is the measure of side EF
Mamont248 [21]

Answer: 48

Step-by-step explanation:

Given

Trapezoid DEFG is dilated by a scale factor of  \frac{2}{3}

E'F'=32

Suppose the length of EF is x

Multiply the side length of DEFG by \frac{2}{3} to form E'F'

\Rightarrow E'F'=x\times \dfrac{2}{3}\\\\\Rightarrow 32=x\times \dfrac{2}{3}\\\\\Rightarrow x=16\times 3\\\Rightarrow x=48

\therefore EF=48

Vedmedyk [2.9K]
X - 25 = 1/3x + 105
x - 1/3x = 105 + 25
2/3x = 130
x = 130 * 3/2
x = 390/2
x = 195 <==== previous weight
