Question

The perimeter of a rectangular field is 74 m. If the length of the field is 19m, find the breadth​

Answer 1

Perimeter of a rectangle = 2(l+b)

l = 19m

2(l+b) = 74m

l + b = 37m

19 + b = 37

b = 37 - 19

b = 18m

Answer 2

Answer:

$2l + 2b = 74 \\ 2(l + b) = 74 \\ 2(19 + b) = 74 \\ 38 + 2b = 74 \\ 2b = 74 - 38 \\ 2b = 36 \\ b = 18 \\ mark \: as \: brainliest \: answer \: plzzz$
