The width of a rectangle is 1 less than one-half its length, and the perimeter is 46. Find the dimensions.
1 answer:
Answer:
Length is 26, width is 7
Step-by-step explanation:
Supposing y= width and x= length
We know from the question that
y= 1/2x -1
And the perimeter of any rectangle is 2y + 2x
Substitute y for 1/2x-1
2(1/2x-1) + 2x = 46
x - 2 + 2x = 46
3x = 48
x= 16
y= (1/2*16)-1
y=7
