We determine the largest possible area of the backyard by multiplying the length and width using the greatest values for each dimensions which is 22 for the length and 32 for the width, or vice versa. 
                                          Area = (32 m) x (22 m)
                                                    = 704 m²
Thus, the answer is 704 m².
Note: The answer given above was obtained by multiplying 31m by 21 m.

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

h =\frac{A}{b}

Here’s why:  

⸻⸻⸻⸻

\boxed{\text{Solving for 'h'...}}\\\\A=bh\\----------\\\rightarrow bh = A\\\\\rightarrow \frac{bh=A}{b}\\\\\rightarrow \boxed{h=\frac{A}{b}}

Hope this helps you. I apologize if it’s incorrect.

How long would it take to earn $6,000 in interest on a principal of $9,000 at an annual simple interest rate of 4.1%? Use the si
e-lub [12.9K]
Ok so we are given 6000 and I think that would be I
We are also given 9000, and I think that would be p
Also we are given 4.1% or 0.041 and I think that would be r
So the formula is 
I = prt
6000 = 9000*0.041*t                        So we are trying to figure out t, time
6000/0.041 = 146341.463
<span>146341.463/9000 = 16.2601626 
I believe your answer would be</span> <span>16.2601626, please let me know if that's right because I'm really not sure.</span>

Find the unknown side of a rectangle solid. V=30 cm3, H=3 cm, W=5 cm
Alex17521 [72]
V = 30cm³
H = 3cm
W = 5cm
L = ?

V = H × W × L

therefore:
3 × 5 × L = 30
15L = 30
L = 30 : 15
<u>L = 2 (cm)</u>
