The amount of money that Ahmed gave to his brother is AED 140.

It is given in the question that Ahmed has AED 180. He gives his brother 0.7  with bar notation of the amount he has.

We have to find the amount given by Ahmed to his brother.

Here, we have to convert a non-terminating but recurring rational number into fraction form.

Let 0.7 bar = x

Multiplying the equation by 10, we get

7.7 bar  = 10x

10x - x = 7.7 bar - 0.7 bar

9x = 7

x = 7/9

Hence, Ahmed gave 7/9 of the amount he had to his brother.

Hence, we can write,

Amount given to Ahmed's brother by Ahmed = (7/9)*180 = AED 140.

What is the area of this triangle.
chubhunter [2.5K]

Answer:

13 square units

Step-by-step explanation:

You <em>could</em> calculate the length of each side using Pythagorean theorem, then use Heron's formula to find the area.  But there's an easier way: find the area of the rectangle that contains the triangle, and subtract the areas of the smaller triangles in the corners.

The area of the rectangle is 4 × 7 = 28.

The area of the upper left triangle is ½(2)(4) = 4.

The area of the upper right triangle is ½(3)(5) = 7.5.

The area of the lower right triangle is ½(1)(7) = 3.5.

So the area of the triangle is:

28 − 4 − 7.5 − 3.5 = 13
