Complete the steps to find the area of the trapezoid.
Yuki888 [10]

Answer:

Area of rectangle: 256

Area of triangle 1: 24

Area of triangle 2: 16

Area of triangle 3: 96

Area of trapezoid: 120

Step-by-step explanation:

I just did the question on the thing so Ik I'm right.

-The graph measures by twos. To get the area of the rectangle get the base times height of it. That would be 16x16=256.

-Get base (8) times height (6) of triangle 1 then divide by 2, remember to count the squares by 2 for finding all areas. The formula would be 1/2(b)(h) because dividing by 2 is the same as multiplying times 1/2. Plug it in and     (8)(6)=48 then divide by 2 which equals 24.

-Same formula for triangle 2. Plug it in and (8)(4)=32 and divide by 2 and it equals 16.

-Same formula for triangle 3. Plugged in is (12)(16)=192 divide by 2 and it equals 96.

-To find the area of the trapezoid get your rectangle area (256) and subtract all the triangle areas. So 256 - 6 - 16 - 96 = 120.

<h3><u>Answer</u> :- </h3>

c) 0.01

<h3><u>Solution</u> :-</h3>

To Write percentage in decimal or fraction we divide it by 100

therefore,

\begin{gathered}\\\implies\quad \sf 2\% = \frac{2}{100} \\\end{gathered}

\begin{gathered}\\\implies\quad \sf 2\% = 0.02 \\\end{gathered}

Half of 0.02 = \sf\frac{1}{\cancel2} \times\cancel{0.02}

\implies\boxed {0.01}
