315 m²

<u><em>area of rec + area of rec + area of rec +  area of triangle</em></u>

⇒ length + width + length + width + length + width + 1/2 * base * height

⇒ 19 * 6 + 9 * 9 + 18 * 5 + 1/2 * 12 * 5

⇒ 90 + 30 + 81 + 114

⇒ 315 m²

Answer:

<u>315 m²</u>

Step-by-step explanation:

As this figure may seem complicated, we can split it into four separate figures.

<u>Area</u>

  • Area of vertical rectangle + Area of left horizontal rectangle + Area of right horizontal rectangle + Area of triangle
  • 6 x 10 + (9 + 6) x (19 - 10) + 18 x 5 + 1/2 x 12 x (18 + 9 + 6 - 17 - 11)
  • 60 + 15 x 9 + 90 + 6 x 5
  • 60 + 135 + 90 + 30
  • 180 + 135
  • <u>315 m²</u>

3m+n=10<br>5m-2n=2<br>what is the answer for this one ​
svlad2 [7]

Answer:

m = 2

n = 4

Step-by-step explanation:

Ok so to solve this, you want to get it so there is only one variable and then solve that equation. To do this, you can start by doing:

3m + n = 10

multiply both sides by 2

6m + 2n = 20

now, in both of your equations you have 2n so you can add the two equations:

6m + 2n = 20

+ 5m - 2n = 2

11m = 22

divide both sides by 11

m = 2.

Now, plug this value into the original equation, 3m + n = 10:

3 * 2 + n = 10

6 + n = 10

subtract 6 from both sides

n = 4

Total number of faculty is 136. There are 6 professors to every 11 lecturers. How many professors are there
laila [671]

Answer:

The Total number of Professors = 48  

Step-by-step explanation:

Given as,

The total number of Faculty = 136

And the Ratio of Professors to Lecturers = 6 Ratio 11

Now According to question

Professors : Lecturers = 6 : 11

So, Let the Number of Professors = 6x

And      The Number of Lecturers = 11x

∴ 6x + 11x = 136

  Or,   17x = 136

   Or,      x = \frac{136}{17} = 8

Hence, the number of Professors = 6 × 8 = 48       Answer

Answer:

76 m²

Step-by-step explanation:

The figure has been decomposed into 3 rectangles as shown in the attachment. Therefore:

Area of the figure = area of rectangle 1 + area of rectangle 2 + area of rectangle 3

✔️Area of rectangle 1:

Area = L*W

L = 2 m

W = 4 m

Area = 2*4 = 8 m²

✔️Area of rectangle 2:

Area = L*W

L = 4 m

W = 6 - 4 = 2 m

Area = 4*2 = 8 m²

✔️Area of rectangle 3:

Area = L*W

L = 10 m

W = 6 m

Area = 10*6 = 60 m²

✅Area of the figure = 8 + 8 + 60

= 76 m²
