Answer:
g=2160
Step-by-step explanation:
multiply both sides by 12
180*12=2160
g=2160
Let the width be x, the length is then 3x-10
Area of a rectangle is length times width: x(3x-10)=77 => 3x^2-10x-77=0
Factor this quadratic equation: (x-7)(3x+11)=0 =.x=7 or x=-11/3
width cannot be negative, so the only answer is x=7
width is 7m, length is 11m
Answer:
60
Step-by-step explanation:
The multiples of 10 are 10,20,30,40,50,60,70 etc.
The multiples of 12 are 12,24,36, 48, 60
The smallest number which is a multiple of both 10 and 12 is 60
