<span> The triangle seems to be a scalene triangle because all three of its sides are different. </span>
First bring all terms in 'a' to the left side of the formula by subtracting ac from both sides
ab - ac - cd = ac - ac
ab - ac - cd = 0
now add cd to both sides
ab - ac -cd + cd = cd
ab - ac = cd
now factor the left side by taking out the 'a'
a(b-c) = cd
now divide both sides by (b-c)
a = cd / (b-c)
done
The area surface is “20,736”
it would be 0.254.
you have to convery the millimeter to meters
You should send a clearer picture. I have problems reading this.
