Answer:
a=10.35
Step-by-step explanation:
Hey There!
All you have to do is plug in the L and W value
a= 4.5(2.3)
4.5x2.3=10.35
so a=10.35
Dividing by 2, we have S/2=lw+lh+wh. After that, we subtract lh from both sides to get S/2-lh=lw+wh. Next, we divide both sides by w to get (S/2)/w=l+h. Next, we divide by S/2 to get 1/w=(l+h)/(S/2). Lastly, we multiply by w and divide by (l+h)/(S/2) to get w=(S/2)/(l+h)
