The length of a rectangle is 2a. The width is 3a - 4. Find the area of the rectangle in terms of the variable x?
The area, in terms of a, is 2a*(3a-4) = 6a2-8a However, it is not possible to give its area in terms of x without knowing anything about x, such as how x relates to a.
What happens to the area when the length of a side is trippled?
If you are refering to a rectangle or paralellogram the the area will be 3 times. L x W = A 3L x W = 3A
How do you write simplified expressions for the area and the perimeter of a rectangle one side 3a other side 5b?
Area: 15ab Perimeter: 2(3a+5b) or as 6a+10b
What are the dimensions of a rectangle when one side is 1.5 cm longer than the other side and its area in numerical terms is the same as its perimeter?
l = w + 1.5p = 2(l + w) = 4w + 3a = lw = w2 + 1.5ww2 + 1.5w = 4w + 32w2 + 3w = 8w + 62w2 - 5w - 6 = 0Quadratic formula gives w = 3.38 so l = 4.88, making a = 16.49P = 2 (3.38 + 4.38) = 16.52. Near enough for Wiki!Improved Answer:Let the length be (x+1.5) and the width be x:length*width = 2(length+width)(x+1.5)*x = 2(x+1.5+x)x2+1.5x = 4x+3x2+1.5x-4x-3 = 0x2-2.5x-3 = 0Solving the above quadratic equation gives a positive value of 3.386000936 for x.Therefore: length = 4.886000936 cm and width = 3.386000936 cmCheck: length*width = 16.54400374 cm2 and 2(length+width) = 16.54400374 cm
What is a plus 3a-2 plus 3a simplified?
7a minus 2, if "3a-2" means 3a minus 2. 3a plus 1 and 1-3rd in parenthesis times 3a, if "3a-2" means 3a squared. a plus 3a squared plus 3a = 1-3rd times 3a plus 3a times 3a plus 1 times 3a = 3a plus 1 and 1-3rd in parenthesis times 3a
