Problema Solution
The length of a rectangle is twice the width. The area is 328 square centimeters. Find the length and width.
Answer provided by our tutors
Let
l = the length of the rectangle, l>0
w = the width of the rectangle, w>0
A = 328 cm^2 the area of the rectangle
The length of a rectangle is twice the width:
l = 2w
The area of the rectangle is A = l*w
l*w = 328
plug l = 2w into the last equation:
2w*w = 328
........
........
w = 12.81 cm
l = 2*12.81
l = 25.62 cm
The length is 26.62 cm and the width is 12.81 cm.
