Doubling the side-lengths will multiply the area by four.
Proof:
Let the side-lengths of the rectangle by x and y. Clearly, the area will be x*y=xy. The new rectangle will have side-lengths 2x and 2y, and thus area 2x*2y=4xy. 4xy/xy=4 - hence, the new rectangle has four times the area of the old one.
It is probably easier to open an account with a bank rather than with a credit union because most credit unions require a kind of affiliation, but banks will let anyone with money to open an account. The correct option among all the options that are given in the question is the first option or option "a".
Hope this helps!
Answer:
The area of each figure is:
- <u>Area of the rectangle = 10 square units.</u>
- <u>Area of the triangle = 10 square units.</u>
- <u>Area of the figure = 20 square units.</u>
Step-by-step explanation:
To find the area of that figure, first, we're gonna find the area of the rectangle and next the area of the triangle, to make this we need to identify the measurement of each one, the rectangle has 2 units wide and 5 units high, then, we use the next formula:
- Area of a rectangle = width * height
- Area of a rectangle = 2 units * 5 units
- <u>Area of a rectangle = 10 square units</u>
Now, we identify the measurements of the triangle (base = 4 units, height = 5 units) and we use the formula:
- Area of a triangle = (base * height) / 2
- Area of a triangle = (4 units * 5 units) / 2
- Area of a triangle = (20 square units / 2
- <u>Area of a triangle = 10 square units</u>
And we obtain the area of the whole figure when we add the two areas:
- Area of the figure = area of the triangle + area of the rectangle
- Area of the figure = 10 square units + 10 square units
- <u>Area of the figure = 20 square units</u>.
As you can see, <u><em>the area of the picture is 20 square units</em></u>.
