What is the area of the square whose side measures 2x-5 cm?
It is: (2x-5)(2x-5) = 2.5 square cm when solved as a quadratic equation
A rectangle has length of 2x-5 units and a width of x-3 units what is the area in square units of the rectangle?
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 area of the garden is 50 square feet and the length of the garden is twice the width What is the length of the fence?
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
What percentage of the square is occupied by the circle when it is inscribed in a square and tangent at all four sides?
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%.
What is the area of a rectangle with a length of 12 and a perimeter of 30?
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
