Question about Lands Phones
Let x be the width and y be the length
we know that the length (y) is 8 inches more than the width (x)so y = x + 8
we know that the total perimeter 60cm (23.622 inches)
so 2x + 2y = 23.622
substituting for y gives
2x + 2(x + 8) = 23.622
2x + 2x + 16 = 23.622
4x = 7.622
x = 1.9055
therefore the rectangle is width 1.9055 inches and length 9.9055 inches
