Solve each formula for the specified variable

lord [1]

Answer:

$\frac{A-2wh}{2(w+h)}=l$

Step-by-step explanation:

We have to find the formula for the value of 'l'.

So, we will isolate 'l' on one side of the formula.

A = 2lw + 2lh + 2wh

A = 2l(w + h) + 2wh

A - 2wh = 2l(w + h) + 2wh - 2wh

A - 2wh = 2l(w + h)

$\frac{A-2wh}{2(w+h)}=\frac{2l(w+h)}{2(w+h)}$

$\frac{A-2wh}{2(w+h)}=l$

Therefore, formula for 'l' will be,

$\frac{A-2wh}{2(w+h)}=l$
