Answer:

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

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)

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

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

Therefore, formula for 'l' will be,

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