It is: (2x-5)(2x-5) = 2.5 square cm when solved as a quadratic equation
a rectangle has a length of 2x-5 units and a width of x-3 units. what is the area, in square units, of the rectangle?
The formula for finding the area of a rectcngle is: L * W = A Let x represent the width and 2x represent the length (twice the width). Set up the equation and solve: 2x * x = 50 (then simplify) 2x² = 50 (then divide both sides to find the value of x²) x² = 25 (then find the square root of 25 to solve for x) x = 5 the width (x) = 5, and the length (2x) = 10
Say the radius of the circle is x. This makes the area of the circle pi x2. Since the length of the square's sides is the diameter of the circle, 2x, its area is 2x * 2x = 4x2. The percentage occupied by the circle is the area of the circle divided by the area of the square times 100 pi/4 x 100; pi/4 x 100 = 100pi/4 = 25pi = 78.6%.
First we have to find the width. Let the width be x: 2(12+x) = 30 24+2x = 30 2x = 30-24 2x = 6 x = 3 So the width is 3 units Area = length*width = 12*3 = 36 square units
