Question 909362: Thank you for helping me! There are three questions on my homework which I have tried and failed could you please help me with them.
Question one is: Rectangle A has one side which is 6cm long and the other is (x+2)cm long. Rectangle B has sides of length (2x+1)cm and 3cm. If the perimeters are the same, calculate the value of x and hence, the lengths of the sides of the triangles.
I have tried to work out this question, making x four but this does not work as it gives me sides of 6 and 6 on triangle A.
My Second question is that: Rectangle X measures 7cm by (x+1)cm. Rectangle b has dimensions of (3x+6)cm and 4cm. The area of rectangle X is half the area of rectangle B. Calculate the lengths of the sides of the rectangles and their areas. (Please reply as soon as possible, thanks)

Question 909572: Question: A rectangle has an area of 330 meters squared. one side is 7 meters longer than the other. what are the dimensions of the rectangle?
My Attempt: x(x+7) = 330
x^2 + 7x = 330
square root both sides x + 7x = 18.2
8x/8 = 18.2/8
x = 2.25
It's wrong.
