Step-by-step explanation:
use herons formula
√s(s-a)(s-b)(s-c)
where s is the semi perimeter
S=20
and a,b,c are sides of triangle
=√20(20-17)(20-9)(20-14)
=√20.3.11.6
=62.92
nearest whole number is 63
option B is correct
Answer:
S=a^2
Step-by-step explanation:
Note all sides of a square are equal, and the formula for finding the area is length x width of which the length=a and the with =a. So S=a^2.
V = LWH.....to find W, divide both sides by LH
V / LH = W <===
If you mean 1/3 the answer is -15.5
1/3(-32.48-14.02) = 1/3(-46.5) = (-15.5)
