Ok so if you follow the process of pemdas is should be easy pemdas equals: parentheses, exponents, multiple and divide from left to right, lastly add and subtract from left to right
Ok, so...what is the question?...
L=w+2 and 2w+2l=44
substitute equation for length in perimeter equation
2w+2(w+2)=44
2w+2w+4=44
4w+4=44
4w=40
w=10
substitute width into length equation to get length
l=10+2
l=12
a=lw
a=12*10
a=120 cm^2
