Question

a graphic designer is making a logo using rectangles with a height-to-width ratio of 4 : 5. Write an equation that can be used to find the height of the rectangles when the width is known

Answer 1

The  equation that can be used to find the height of the rectangles when the width is known is h = P - 4

How to find the perimeter of the rectangle

perimeter of rectangle = 2(l + h)

P(l, h) = 2(l + h)

Since the perimeter = 2(4+5) = 18, then;

18 = 2(4 + h)

9 = 4 + h

h = 9 - 4

h = P - 4

Hence the  equation that can be used to find the height of the rectangles when the width is known is h = P - 4
