if the length of a rectangle is 6 times the width, and the perimeter is 210 cm, find the dimensions of the rectangle

Respuesta :

Answer:im not sure but it’s 180Cm

Step-by-step explanation:worked it in my head

Answer: x = width

2x - 3 = length

2w + 2l = perimeter

2(x) + 2(2x - 3) = 210

2x + 4x - 6 = 210

6x - 6 = 210

6x = 216

x = 36

2(36) - 3 = y

72 - 3 = y

69 = y

width = 36 cm

length = 69 cm
