What is the area of this quadrilateral?
sertanlavr [38]

Answer:

The area of the quadrilateral is 12 square feet. (B)

Step-by-step explanation:

To find the area of a triangle, we use the formula (L x W) / 2

The bottom triangles are both the same size, so we only need to find the area of one. The width of the triangle needs to be divided by two because we only need to know half of the big triangle on the bottom at the moment. So we have (3 x 2) / 2 = 3. We can then multiply that by two and the area of the bottom triangle is 6. To solve for the top, (3 x 4) / 2 = 6. We can then add together the top and the bottom to get B, 12 square feet.

Hope this helps!

kirza4 [7]

Answer:

45 Kg of the of this mixture contains 9 kg of almond

Step-by-step explanation:

Given:

The ratio of  almond, wheat and corn = 3:5:7.

To Find:

Amount of this mixture contains 9 kg of almond =?

Solution:

The total of  the fraction = 3+5+7  = 15

Let the total amount of the mixture be X, then

Then

\frac{ \text{ratio of the almond in the mixture}}{\text{total ratio}}  \times X = 9

\frac{3}{15} \times  X  = 9

X = 9 \times \frac{15}{3}

X = 9 \times 5

X =  45
