The area of a triangle is given in terms of the side lengths (b, h) as
... A = (1/2)bh
If b=h, then we can find the side length as ...
... A = (1/2)b²
... b = √(2A) . . . . . multiply by 2 and take the square root
The hypotenuse (x) can be found from the Pythagorean theorem:
... x² = b² + h² = 2b²
... x = b√2
The perimeter is the sum of the side lengths, so is
... P = b + b + x = 2√(2A) + (√(2A))·√2
... P = (2+√2)·√(2A)
Answer:
Step-by-step explanation:
Given
= 
= 
× 
← cancel (x + 50)(x + 1) on numerator/denominator
=
<span><span>9/8</span>=1<span> 1/8</span> miles</span>
To calculate the total distance walked, sum the 2 individual distances walked together.
<span>⇒<span>34</span>+<span>38</span></span>
We require to have common denominators, before adding.
<span><span>34</span>×<span>22</span>=<span>68</span></span>
<span>⇒<span>68</span>+<span>38</span>=<span>98</span>=1<span><span>18</span></span></span>
