A rectangular room is 3 meters longer than it is wide, and its perimeter is 22 meters. Find the dimension of the room. The length is : meters and the width is: meters.

Width = 4 m

Length = 7 m

Step-by-step explanation:

given:

perimeter of a rectangle = 22m

L = 3 + W

perimeter = 2L + 2W

perimeter = 2 (3 + W) + 2W

22 = 6 + 2W + 2W

22 - 6 = 4W

W = 16 / 4

W = 4 m

L = 3 + W

L = 3 + 4

L = 7 m

check:

perimeter = 2L + 2W

22 = 2(7) + 2(4)

22 = 14 + 8

22 = 22   OK

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.

the equation is not included but the answer is (1.50, 2.00, 2.75)
