Find the area of a triangle whose height is 2x and base is 2x + 2.

wel

Answer: $2x^{2}+2x$

Step-by-step explanation:

1. You must apply the formula for calculate the area of a triangle, which is shown below:

$Area=\frac{base*height}{2}$

2. You know the height and the base, which are given in the problem. Then, you only need to substitute them into the equation shown above and simplify it, as following:

$Area=\frac{2x(2x+2)}{2}$

$Area=x(2x+2)\\Area=2x^{2}+2x$

Erika is painting a rectangular painting. The painting has a length of 12 and a width of 10 inches. Use the Distributive Propert

antiseptic1488 [7]

Given:

Length of the painting = 12 inches

Width of the painting = 10 inches

To find:

The area of the rectangular painting by using Distributive Property to decompose the factor 12.

Solution:

The area of a rectangle is

$A=length\times width$

So, the area of the rectangular paining is

$A=12\times 10$

Using Distributive Property to decompose the factor 12, we get

$A=(10+2)\times 10$

$A=(10\times 10)+(2\times 10)$

$A=100+20$

$A=120$

Therefore, the area of the rectangular painting is 120 square inches.
