perl · Answer

Let
S = side of square
L = length of rectangle
W = width of rectangle 

We are given 

3S = 48 
L- W = 7
W = s

can you solve it now

perl · Answer

hint, first solve for S

surryyy · Answer

s = 48/3
s = 16

L = s + 7
L = 16 + 7
L = 23 is the length of the rectangle

is it correct?
