Question

The length of a rectangle is 6 cm longer than the width. the perimeter of the rectangle is 92 cm. find the length and the width of the rectangle.

Answer 1

taking that the width is x

width: x cm
length: (x+6)cm
perimeter:

`92 = 2((x + 6) + x)`
hence,

`4x = 92 - 12 = 80`
therefore, x=20

hence, since the width is 20cm, the length would be 26cm
