write an eqation and solve it to find the length and width of the

Question

the length of a rectangular paddock is 7 m less than twice the width. If the perimeter is 58 m

Answer 1

Emaily, how do we find perimeter? 2(l + w), right?

 

l = 2w - 7

 

58 = 2(2w - 7 + w)

58 = 4w - 14 + 2w

72 = 6w

w = 12

 

l = 2(12) - 7

l = 24 - 7

l = 17

 

The length is 17m and the width is 12m.
