Answer:
5.42
It is this because 7.52-2.9 is equal to 4.62 plus 0.8 equals 5.42.
Answer:
If you divide 95 by 4 its 23.75
Step-by-step explanation:
Area of a triangle = height x base ÷ 2
When ever you have an isosceles triangle, remember that you can split it in half to form two right angled triangles - which allow you to use Pythagoras' Theorem.
So we split 10cm in half to get 5cm.
We can then use 13cm and 5cm to work out the height:
Height = √(13² - 5²) <em>(Note: you subtract because you are using the </em>
= √144 <em>(hypotenuse)</em>
<em> = </em>12
---------------------------------------------------------
Now to get the area, we just multiply the base (which is 10) by the height (which is 12) and divide by 2:
Area = 12 x 10 ÷ 2
= 6 x 10 <em>(note: 12 ÷ 2 = 6 )</em>
= 60 cm²

Answer:
60 cm²
Check the picture below.
now, to get how much is the area of the tiled section, we simply get the area of the whole pool, 53x26, which includes the tiles, and then subtract the area without the tile, the rectangle in the middle, and what's leftover, is the area of the tiled area.
The answer is 6 square feet, HAPPY HOLIDAYS
