Question

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

Answer 1

Answer:

26 cm

Step-by-step explanation:

we can make an equation to find the lengths

2(x+7x-2) = 60

x : length of width

7x-2 : the length of length

2 : the two pairs of length and width

solving this equation, we get x = 4

but that is not the answer

we have to plug in x=4 into 7x-2

7*4-2 = 28-2 = 26
