Step-by-step explanation:
84 = 2(l+b)
L+b = 84 / 2
L+b = 42
There fore..
Length is 42 and breadth is 42 - 8
A^2+b^2=c^2 (Pythagoran theorem)
-> 30^2 + length^2 = 78^2
-> length = √6084-900 = <span>√5184 = 72 ft
=> area = length x width = 72 x 30 = 2160 ft^2</span>
14, because the percentage of -x to y is not equivalent so when u divide it, u get 14.
The answer is A- 35/84
Proportional means that two things are equivalent to each other
Therefore, the ratio 10/24 has to be equal to another fraction
So when you put these fractions side by side 10/24 = 35/84 you multiply the #'s to see if this is correct
so 10 * 84 = 840 and 24 * 84 = 2016 then 35 * 24 = 840 and 84 * 24 = 2016
So the fractions now are 840/2016 = 840/2016
We can easily see that these fraction are proportional (equal)
Therefore the answer is once again 35/84
