Answer:
580 seedlings altogether.
Step-by-step explanation:
Given that,
Ali plants 40% of the total number of seedlings, Ben plants 45% of the total number of seedlings, and Cliff plants the rest of the seedlings. Cliff plants 87 seedlings.
The percentage of the seedling planted by Cliff = 100% - 45% - 40% = 15%
<em>Let x = the total number of seedlings</em>
<em />![15\%\ of\ x=87\\\\x=\dfrac{87\times 100}{15}\\\\x=580](https://tex.z-dn.net/?f=15%5C%25%5C%20of%5C%20x%3D87%5C%5C%5C%5Cx%3D%5Cdfrac%7B87%5Ctimes%20100%7D%7B15%7D%5C%5C%5C%5Cx%3D580)
Hence, three boys plant 580 seedlings altogether.
to find the area of a rectangle is LxW=A
plug in the given numbers you have
L = 7
W = x-8
A = 42
7 * x-8 = 42
7x-56= 42
solve for X
