Question

the length of a rectangle is 2cm less than 7 times the width. the perimeter is 60. find the length and width.

Answer 1

where are you stuck ?

Answer 2

the equation

Answer 3

call the width 'w', then:
7 times the width = 7w
2cm less than 7 times the width = 7w-2
so width = w
length = 7w-2

Answer 4

length is 7x-2
width is x
2(x)+2(7x-2)
2x+14x-4=60
16x=60+4
16x=64
x=4 which is width
now for length which is 7(4)-2=26
