Answer:
Step-by-step explanation:
The formula for area of a triangle is
Now we have to isolate for w.
First multiply by the 2 which is the reciprocal of 1/2 to cancel it out.
Now divide by h to isolate w.
Here are the answer: a) R = 3.6 and b) A = 2
Step-by-step explanation:
Given,
R is inversely proportional to A.
R ∝
so, R = -------eq 1 where k is any constant
To find the values of a) R when A = 5 and
b) Value of A when R = 9
Now,
Putting R = 12 and A = 1.5 in eq 1 we get,
12 =
or, k = 12×1.5 = 18
From eq 1 we get,
R = --------- eq 2
Now,
a) Putting A= 5 in eq 2 we get,
R = = 3.6
b) Putting R = 9 in eq 2 we get
R =
or, A = = 2
