Question

the length of a rectangular field is 8 meters less than twice its breadth vif the perimeter of the rectangular field is 56 meters find its length and breadth?​

Answer 1

Answer:

b = 12m and l = 16m

Step-by-step explanation:

Given that length = 2b - 8

perimeter = 2 (l + b) = 56

2 (2b - 8 + b) = 56

2 (3b - 8) = 56

6b - 16 = 56

6b = 56 + 16

b = 72 / 6 = 12

l = 2 * 12 - 8 = 24 - 8 = 16m
