kolbaska11 [484]

Hey there,

We know that area is the size of a surface

First of all, To find the area of a rectangle, multiply the length by the width. In this question the length would be 90 meters and the width would be 45 meters.

90 x 45 = Area

90 x 45 = 4050

Area = 4050m²

Simplify the following expression (30/45g+20)-(8/9g+7)

den301095 [7]

The answer is: $13-\frac{2}{9}g$

The explanation is shown below:

1- You have the following expression given in the exercise:

$(\frac{30}{45}g+20)-(\frac{8}{9}g+7)$

2- When you multiply signs, you obtain:

$\frac{30}{45}g+20-\frac{8}{9}g-7$

3. Now, you must add like terms, as following:

$-\frac{2}{9}g+13$

4. Therefore, you have that the expression simplified is:

$13-\frac{2}{9}g$
