Question

The perimeter of a rectangle is 72 centimeters. The base is 3 times the height. What are the dimensions of the rectangle?


a.

h = 3 cm, b = 9 cm

c.

h = 9 cm, b = 27 cm



b.

h = 4 cm, b = 12 cm

d.

h = 5 cm, b = 15 cm

Answer 1

Perimeter = x + 3x + x + 3x = 72

where x = shorter lenght
3x = longer length

since 8x = 72, x = 9, 3x = 27

and the area is 27 times 9 or 243

Answer 2

SO YOU ARE GOOD AT MATH LOL

Answer 3
