Kirti has developed formulas to help her determine the size of her rectangular flower garden each spring. If she wants to plant

Ksju [112]

Answer:

A(n) = L(n) × W(n) and $A(n)=0.5n^{2} +2n+2$

Step-by-step explanation:

We are given that the length of the rectangular garden is L and width is W.

Also, in terms of 'n',

Length is given by, L(n) = n + 2

Width is given by, W(n) = 0.5n + 1.

Now, we know that, Area of rectangle = Length × Width.

Therefore, area of Kirti's garden is given by, A(n) = L(n) × W(n).

Thus, formula of area in terms of L(n) and W(n) is A(n) = L(n) × W(n).

Moreover, as A(n) = L(n) × W(n).

i.e. A(n) = (n+2) × (0.5n+1)

i.e. $A(n)=0.5n^{2} +n+2 \times 0.5n+2$

i.e. $A(n)=0.5n^{2} +n+n+2$

i.e. $A(n)=0.5n^{2} +2n+2$

Hence, the formula for area in terms of 'n' is $A(n)=0.5n^{2} +2n+2$ .

What is the length of a diagonal brace that could be used for a wall 9 feet high and 12 feet long

kolbaska11 [484]

You use the pythagorean theorem to solve this problem. The theorem is a^2+b^2=c^2, where c^2 is the length of the hypotenuse of the triangle, or the side that's the longest and is opposite the right angle of the right triangle. Note that this theorem is applicable because a wall has right angles and it is assumed that the diagonal brace would form a right triangle (the diagonal brace is the hypotenuse). Next, you substitute the values of 9 and 12 for a and b, and then you proceed to solve this algebraically to get c after taking the square roots of both sides of the equation to get c from c^2.

The length of a rectangular garden is 10 feet longer than its width. The garden's perimeter is 208 feet. Find the width of the g

Yuliya22 [10]

The answer is
work:
208/2 = 114
now this is easier.
the answer is 62, as 62 is 10 more than 52, so once added,(obviously) that gets you 114, and the width is 52.
