Answer:

83 in.^2

Step-by-step explanation:

The entire polygon consists of a rectangle with length 8 in. and width 5 in., a triangle with base 8 in. and height 7 in., and another triangle with base 5 in. and height 6 in.

The total are is the sum of the area of the rectangle and the two triangles.

area = area of rectangle + area of first triangle + area of second triangle

area = LW + bh/2 (for the first triangle) + bh/2 (for the second triangle)

area = 8 in. * 5 in. + 8 in. * 7 in. / 2 + 5 in. * 6 in. / 2

area = 40 in.^2 + 28 in.^2 + 15 in.^2

area = 83 in.^2

If 7/12 is multiplied by a fraction less than 1 what would be the product

olga55 [171]

Answer:

<em>Examples below</em>

Step-by-step explanation:

We have the fraction

$\frac{7}{12}$

It's required to multiply it by any fraction less than 1. Let's select the following fractions. All of them are less than 1 because the numerator is less than the denominator:

$\frac{1}{7}$

$\frac{4}{5}$

$\frac{6}{35}$

The required products are:

$\frac{7}{12}\cdot \frac{1}{7}=\frac{7}{7*12}=\frac{1}{12}$

$\frac{7}{12}\cdot \frac{4}{5}=\frac{4*7}{12*5}=\frac{7}{15}$

$\frac{7}{12}\cdot \frac{6}{35}=\frac{6*7}{12*35}=\frac{1}{10}$

Would appreciate some help with this question, I am struggling!

ValentinkaMS [17]

I think you would multiply 14m x 9m which is 126m and then you would multiply 2.4m and 3.8m which is 9.12m. Last you would subtract 9.12m from 126m which is 116.88m...I’m sry if this isn’t correct
