The length of a rectangle is twice the width. The area is 338 yd. Find the length and the width. August 29, 2021 by Maris The length of a rectangle is twice the width. The area is 338 yd. Find the length and the width.
The width is 13 and the length is 26. Explanation: Area of rectangle = length x width Let x be the width of the rectangle and 2x be the length of the rectangle. 2x * x= 338 2x² = 338 x² = 338/2 x² = 169 x² – 169 = 0 (x)² – (13)² = 0 (x-13)(x+13) = 0 x – 13 = 0 or x + 13 = 0x = 13 or -13 -13 is rejected, as length or width cannot be negative. Ans:The width is 13 and the length is 2 x 13 = 26. Reply
The width is 13 and the length is 26.
Explanation:
Area of rectangle = length x width
Let x be the width of the rectangle and 2x be the length of the rectangle.
2x * x= 338
2x² = 338
x² = 338/2
x² = 169
x² – 169 = 0
(x)² – (13)² = 0
(x-13)(x+13) = 0
x – 13 = 0 or x + 13 = 0
x = 13 or -13
-13 is rejected, as length or width cannot be negative.
Ans:The width is 13 and the length is 2 x 13 = 26.
