Question 293032: Find the value of x. If necessary, round to the nearest tenth
This is the way I'm thinking to solve it.
sqrt(28) = 5.2915
Rounded 5.3
5.3*5.3 = 28.09...rounded to 28.
Is that how I would solve it? Answer by unlockmath(1688) (Show Source):
You can put this solution on YOUR website! Hello,
Yes, you got the right idea but missed an important value. Let's do step by step so it's clear.
We know the area of a triangle is 1/2(base x height) so we can plug in the values known as:
28=x(x)(1/2) Or rewritten as:
28=x^2/2 Multiply each side by 2 to get:
56=x^2 Square root each side to get:
x=sqrt 56 Or
x=7.48 inches (rounded off)
