P=2(l+w)
50=2(4+w)
50=8+2w
collect the like terms 50-8=2w
42=2w divide both sides by 2
w=21
Answer:
144
Step-by-step explanation:
48 ÷ 4 (which is how many sides a square has) is 12
So 12x12 because l×w (length and width) and all sides of a square are equal
So the answer would be 144

So, let's start off with h
The expression needs to be '3 more than h'
This can be written as:
h + 3
The expression also needs to be 'five times' this value
This can be written as:
5(h + 3)
That would be your answer ^^
Have A Nice Day ❤
