Answer:
Area = 36 
Step-by-step explanation:
There must be an error with the statement, because it is strange that the length of the frame is equal to its thickness.
Assuming that the data supplied is correct, we can do the following procedure.
Let's call L the length of the frame.
We know how much each side of the square measures.
L = 3 inches
We also know that the thickness (s) is:
s = 3 inches.
Then the area of the frame is equal to:
Area = Perimeter * thickness
Area = 4L*s
Area = 3*4*3
Area = 36 
Answer:
X=70
Step-by-step explanation:
Interior angles of parallel line sum up to be 180° so:
45+(2x-5)=180
45+2x=185
2x=140
x=70
Let the length and breadth of the rectangle be x and y.
Area of rectangle is A = xy
Therefore, the new length will be = x-5
Therefore, the new breadth will be = y + 3
So new area will be xy-9
Now the new relation will be (x+3)(y+2)=xy+67
.
Cross – multiplication method–



Therefore, the length is 17 and breadth is 9.
