Question

A rectangle has a perimeter of 82. If the width of the rectangle is one less than twice the length , find the width of the rectangle .

a. 12
b. 14
c. 23
d. 27
​

Answer 1

ans:- 14

Explanation:

let length = x

so, width= 2x -1

perimeter= 2(l +b)

82 = 2(x+ 2x-1)

41 = 3x - 1

3x = 42

x = 14
