Question

Larry wants to buy some carpeting for his living room the length of the room is 2 times width and the total area of the room is 8 square meters what is the length of the living room

Answer 1

Draw a diagram! Lets say the width is x, then the length must be 2x.

Area = length x width
2x x x = 8sq meters
2x^2 = 8
x^2 =4
x = √4
x = 2

we found the width the length is two times the width, making it 4 meters.
