What is the area of the following polygon?

muminat

The area of the polygon is 25.5 square units

<h3>How to determine the area of the polygon?</h3>

From the figure, we have the following coordinates

A = (-2, 1)

B = (3, 2)

C = (5, -3)

D = (-1, -3)

The area of the polygon is then calculated as:

A = 0.5 * |(x1y2 - x2y1) + (x2y3 - x3y2) + (x3y4 - x4y3) + (x4y1 - x1y4)|

Substitute the known values in the above equation

Area = 0.5 * |(-2 * 2 - 3 * 1) + (3 * -3 - 5 * 2) + (5 * -3 + 1 * -3) + (-1 * 1 + 2 * -3)|

Evaluate the sum of products

Area = 0.5 * |-51|

Remove the absolute bracket

Area = 0.5 * 51

Evaluate the product

Area = 25.5

Hence, the area of the polygon is 25.5 square units

4 men and 6 boys can finish a piece work in 5 days while 3 men and 4 boys can finish it in 7 days. find the time taken by 1 man

Anon25 [30]

Answer:

Number of days taken by 1 man alone and 1 boy alone are 35 days and 70 days respectively.

Step-by-step explanation:

Let, the work completed by 1 man in 1 day = x and the work completed by 1 boy in 1 day = y.

So, 4 men and 6 boy's 1 day work is $\frac{4}{x}$ and $\frac{6}{y}$

And, 3 men and 4 boy's 1 day work is $\frac{3}{x}$ and $\frac{4}{y}$

Since, 4 men and 6 boys complete the work in 5 days and 3 men and 4 boys complete the work in 7 days.

So, we have,

$\frac{4}{x}+\frac{6}{y}=\frac{1}{5}$

$\frac{3}{x}+\frac{4}{y}=\frac{1}{7}$

Let, $u=\frac{1}{x}$ and $v=\frac{1}{y}$

So, the equations are,

$4u+6v=\frac{1}{5}$ ................(1)

$3u+4v=\frac{1}{7}$ ................(2)

Multiply (1) by 3 and (2) by 4 and subtract the equations, we get,

$2v=\frac{1}{35}$ i.e. $v=\frac{1}{70}$ i.e. $\frac{1}{y}=\frac{1}{70}$ i.e. y = 70.

Substitute value of 'v' in (1) gives,

$4u+\frac{6}{70}=\frac{1}{5}$ i.e. $4u=\frac{-6}{70}+\frac{1}{5}$ i.e. $4u=\frac{8}{70}$ i.e. $u=\frac{8}{70\times 4}$ i.e. $u=\frac{1}{35}$ i.e. $\frac{1}{x}=\frac{1}{35}$ i.e. x = 35

So, the number of days taken by 1 men alone and 1 boy alone are 35 days and 70 days respectively.
