Answer:
length = 14.5 in
Width = 11.50 in
Step-by-step explanation:
Let the length of the picture = x
width be = y
Perimeter P=52
P is given as
P=2(x+y)
56=2(x+y)
x+y=28 (Dividing both sides by 2) ---(A)
Also given that
the length of the picture fram is 3 in greater than the width.
x-y=3 ----(B)
Adding A and B
2x=29
dividing both sides by 2 we get
x=14.5
Putting this in B we get
14.5-y=3y=11.5
