Let the length be l, the width be w, and the area be A. The equation for the area of a rectangle is A = l*w; we know A = 77, so we need to get l in terms of w so we only have one variable to solve for. We're given l = 2w-3, so we can substitute back in:
A=77=(2w-3)*w
77=2w^2-3w
0=2w^2-3w-77
0=(2w+11)*(w-7)
so w=-5.5 or w=7. Since we can't have a negative width, w=7 inches. Plugging back in to our equation for l and w: l=2w-3=2(7)-3=14-3=11, so the length is 11 inches.
Width = 9 inches Length = 30 inches
3 inches times 5 inches = 15 square inches
The area of a rectangle with a width of 9 and length of 23 is 207 square units.
Call the width of the rectangle x. Call the length of the rectangle x + 2. The area of the rectangle would be the length times the width. We know this is 15 square inches. Set up the equation and solve for x. (x +2)x = 15 x2 + 2x = 15 x2 + 2x - 15 = 0 Factor the quadratic equation: (x - 3)(x + 5) = 0 x = 3 or x = -5 Since length can't be negative, discard the answer -5. If x = 3, then the width is 3 and the length is x + 2 or 5. 5 x 3 = 15 which equals the area.
perimeter 24 so length + width half of that ie 12. Length 3 times width must be 9 and width 3.
9 inches
To find the area of a rectangle, multiply the length times the width. The result will be in square inches.
Area of rectangle: 6 times 7 = 42 square inches
The area of rectangle is : 60.0
The area of a rectangle is length times width. If length and width are in inches, the area will be square inches.
Without the dimensions, we won't be able to tell. The area of a rectangle is the length times the width. If those dimensions are in inches, the area will be in square inches.
The area of square is : 256.0
The area of rectangle is : 30.0
To find the area of the rectangle, multiply the length times the width: 1.24 x .67 = .8308 square inches.
Invalid conversion: square inches is a measure of area and inches is a measure of length or distance.If each side of a square is 10 inches long, the area of the square will be 100 square inches. (10*10=100)For any rectangle with an area of 100 square inches, the length of the short side times the length of the long side must total 100.(For instance, a rectangle 4 inches by 25 inches: 4*25=100)
It would have an area of 36 sq. inches. The formula for finding the area of a rectangle is length times width. 6*6=36.
The area of a rectangle is found by using the formula A=LxW (Area equals length times width)The area of a rectangle is calculated by multiplying the length by the width - the result is square measure. A rectangle 6 inches by 8 inches would be 48 square inches in area. (6x8=48)ExampleA=LxWA=4x5A=20
