Question

The length of a rectangular field is 3 more than twice its width. Find the dimensions if its perimeter is 150 m

Answer 1

Step-by-step explanation:

let the width be x

length=2x+3

Perimeter = 2(l+b)

150cm = 2l +2b

150cm = 2(2x+3) + 2x

150cm = 4x +6 +2x

150cm= 6x+6

144cm= 6x

x= 144/6

x= 24

length= 51cm

width= 24cm
