Answer:
Breadth = 10 cm.
Difference in area = 4 cm^2 ( the square encloses more area).
Step-by-step explanation:
The perimeter of the square = 4*12 = 48 cm.
If the length of the rectangle is 14 then
2*14 + 2b = 48 where b is the breadth.
28 + 2b = 48
2b = 20
b = 10 cm.
A square encloses more area than a rectangle for a given length of wire.
Area of the square = 12^2 = 144cm^2 and
area of the rectangle = 14*10 = 140 cm^2.
Answer:
18
Step-by-step explanation:
0.5(w) + 3x
0.5(6) + 3(5)
= 18
The area is 396 square inches.

Good luck!
1) Find sum of (12x+9y) and (-2y)
12x+9y+(-2y)=12x+7y
2) Subtract (4x-3y) from the sum
(12x+7y)-(4x-3y)=12x+7y-4x+3y=8x+10y
3) The answer is 8x+10y
