The area of a rectangular lot is 60msquared if the lenght is 17m larget than the width. Find the lenght and width

Question

The area of a rectangular field is 162m²  . The lenght id twice the width. Find the dimensions of the field?

Answer 1

You have two problems here. The first one I explained in a different posting. 

 

Again, 

 

width x length = Area of a rectangle

 

w (2w) = 163

 

2w² = 162

dividing both sides by 2,

w² = 81

taking the square root of both sides, 

w = ±9

 

Reject the -9 solution since widths cannot be negative. 

 

w = 9 meters and since the lengh is twice the width, l = 18 meters
