Explanation:
let the breadth be x
given,
length = 6m less than 3 times the width = 6 - 3x
perimeter = 148 m
we know,
perimeter = 2l + 2b
after inserting the values we got,
→ 2(6 - 3x) + 2(x) = 148
→ 12 - 6x + 2x = 148
→ -4x = 148 - 12 = 136
→ 4x = -136
→ x = -136/4 = -34
therefore, the dimensions are
length = 6 - 3x = 6 - 3(-34) = 108m
width = x = -34
hope this answer helps you dear take care and may u have a great day ahead!
