Total area of figure 1 = 408

Total area of figure 2 = 54

Total area of figure 3 = 392

Explanation:

Figure 1:

Area of rectangle 1 = l X b

= 16 X 15

= 240

Area of rectangle 2 = l X b

= 24 X (22-15)

= 24 X 7

= 168

Total area of the given figure = 240 + 168

= 408

Figure 2:

Area of rectangle = l X b

= 6 X 4

= 24

Area of triangle = area of 2 right angle triangle

height of the triangle = 10 - 4 = 6

base of the triangle = 5

Area of 2 right angle triangle = 2 X 1/2 X b X h

= 6 X 5

= 30

Total area of the figure = 24 + 30

= 54

Figure 3:

Area of rectangle = l X b

= 28 X 10

= 280

Area of right angle triangle = 1/2 X b X h

= 1/2 X (24-10) X (28-12)

= 1/2 X 14 X 16

= 112

Total area = 280 + 112

= 392

<h3>Area of a square</h3>

A square is quadrilateral with 4 sides. The formula for calculating the area of the shape is given as:

A = L²

Given the following parameters

A = $196x^{12}y^{10}z^6$

Substitute

L² $=196x^{12}y^{10}z^6$
$L=\sqrt{196x^{12}y^{10}z^6}\\L=14x^6y^5z^3$

Determine the perimeter

Perimeter = 4L

Perimeter = 4(14x^6y^5z^3)

Perimeter = $56x^6y^5z^3$

Hence the perimeter of the room will be $56x^6y^5z^3$ feet

6/7 divided by 1 2/5

Alja [10]

In order to multiply or divide a fraction by a mixed numeral, it is best to have them BOTH in fraction form. 1) We'll convert 1 2/5 into an improper fraction. (1×5)+2 = 7/5
Now 6/7 ÷ 7/5
2) when dividing by a fraction, it is the same to multiply by its reciprocal. So flip the second fraction and multiply them: 6/7 ÷ 7/5 = 6/7 × 5/7
3) reduce them: there is nothing on top that reduces with the bottom, so we simply multiply
4) multiply numerators, then multiply denominators and keep them in place: 6×5 = 30, 7×7 = 49
5) so our final answer is 30/49

Answer:

$10\ yd^2$

Step-by-step explanation:

Area Of Compound Regions

When a surface has no regular shape, it can be usually divided into smaller regular parts and add their areas. The surface shown in the figure can be split into 3 smaller rectangles (please refer to the image below).

The area of the yellow part is

$A_y=(1 yd)(3 yd)=3\ yd^2$
