Since area= length•width, for this u would have to divide the area by the width to get the length, i hope this helps
Answer: 2.25 grams
Explanation:
To find the remaining mass of an element, apply the following:
m0 = m/(2^n), where m0 is the remaining mass, m as the original mass and n as the number of half lives that have passed.
we have m, we just have to find n. To find n,
24/6 = 4 half lives have passed.
Applying the first formula,
m0 = (36)/(2^4) = 36/8 = 2.25 grams
Hope this helps, brainliest would be appreciated :)
W = L - 15
WL = 76
(L-15)L = 76
L^2 - 15L - 76 = 0
(L-19)(L+4) = 0
L = 19 or -4
Since a length cannot be negative, the length must be 19 units.
The width is 19-15=4 units.
