Step-by-step explanation:
To work out the volume of this shape you will first need to work out the area of the triangle. To work out the area of the triangle you would multiply the base of 12 by the height of 4.1, which gives you 49.2. You would then need to divide 49.2 by 2, which gives you 24.6. This is because the formula for the area of a triangle is the same as that of a square, however a triangle is half of a square with the same length and width. To work out the volume you would multiply the area of the triangle, which is 24.6 by the height of 9, which gives you 221.4![m^{3}](https://tex.z-dn.net/?f=m%5E%7B3%7D)
1) Multiply 12 by 4.1.
![12*4.1=49.2](https://tex.z-dn.net/?f=12%2A4.1%3D49.2)
2) Divide 49.2 by 2.
![49.2/2=24.6](https://tex.z-dn.net/?f=49.2%2F2%3D24.6)
3) Multiply 24.6 by 9.
![24.6*9=221.4m^{3}](https://tex.z-dn.net/?f=24.6%2A9%3D221.4m%5E%7B3%7D)
Answer:
The area of a rectangle (A) is the product of its length "A" and width or breadth "b". so, Area of rectangle= (a x b) square units
Step-by-step explanation:
<span>"Cary is 8
years older than Dan. In 5 years the sum of their ages wil equal 96. Find both
their ages now. Solve using equations."
x = Dan's age now
x + 8 = Cary's age now {Cary is 8 yrs older than Dan}
x + 5 = Dan's age in 5 years
x + 13 = Cary's age in 5 years </span>
<span>
x + 5 + x + 13 = 96 {in five years the sum of their ages will be 96}
2x + 18 = 96 {combined like terms}
2x = 78 {subtracted 18 from both sides}
x = 39 {divided both sides by 39}
x + 8 = 47 {substituted 39, in for x, into x + 8}
Dan is 39 years old
Cary is 47 years old</span>
