Answer:
Width = 6.5 inches
Length = 10.5 inches
Step-by-step explanation:
Let
"l" be length of rectangle
and
"w" be width of rectangle
Since length of rectangle is 4 inches MORE THAN WIDTH, we can write:
l = 4 + w
The perimeter is sum of all sides, so
Perimeter = l + l + w + w = 2l + 2w
The perimeter is 34, so we can write:
2l + 2w = 34
Putting 1st equation in 2nd, we get equation in "w" and solve for this first:

Width is 6.5 in
Now, l = 4 + w, so
l = 4 + 6.5 = 10.5
Length is 10.5 in

Answer:
Step-by-step explanation:
(a + b)²=a²+2ab+b²
(3x+3y)²= (3x)²+2*3x*3y+(3y)²
=9x² + 18xy + 9y²
=9x² + 9y² + 18xy
= 9*(x²+y²) +18xy
=9*25 + 18*12
=225 + 216
=441
