Just add a similar triangle from the opposite side
Then what happens
- Hypotenuse of this triangle becomes common and diagonal of the rectangle.
Now
Area
- Area of triangle=20/2=10units^2
When you are painting, tiling, wallpapering or doing anything that involves the region inside a figure, you are dealing with the area of the figure.To calculate the area of a triangle, you can use the formula A = 1/2 base*height. This tells you how many square units it takes to cover the region. Once you know the number of square units, you charge $2 for each square unit, so just multiply, and you've got your answer. So A = 1/2 *4*6 = 12 square units and you'll charge 2*12 = $24 for the job.<span>

Answer:
[[274][895][136]]
Step-by-step explanation:
Starting with the middle row, we need a product of two single-digit numbers that is between 53-1 = 52 and 53-9 = 44. Possible products are 5×9=45 and 6×8=48. This means the number in the middle position in the left column must be 8 or 5.
The middle number in the left column cannot be 5, because we must be able to get -5 by subtracting that number from a sum that is at least 3 = 1+2. So, the middle number in the left column is 8, the other two numbers in that column are 1 and 2, and the other two numbers in the middle row are 5 and 9.
There is no product of single-digit numbers that is 30-1 = 29, so the upper left number must be 2, and the bottom left number must be 1. The other two numbers on the top row must be 4 and 7, so that row's equation is 2+4×7=30.
The only remaining digits are 3 and 6. In order to have -3 on the bottom row, the equation there must be 1×3-6 = -3. Then the middle digit must be divisible by 3, so must be 9.
Our solution is ...
row 1: 2 + 7 × 4 = 30
row 2: 8 + 9 × 5 = 53
row 3: 1 × 3 - 6 = -3
And that makes the column equations be ...
col 1: 2 - 8 + 1 = -5
col 2: 7 + 9 / 3 = 10
col 3: 4 × 5 - 6 = 14
