The perimeter of a rectangle is twice the
masya89 [10]

Answer:

The length is 14 m.

Step-by-step explanation:

length = L

width = W

perimeter = P

"The perimeter of a rectangle is twice the  sum of its length and its width."

P = 2(L + W)

"The  perimeter is 40 meters"

40 = 2(L + W)

"and its length is 2  meters more than twice its width."

L = 2W + 2

Replace L with 2W + 2 in equation 40 = 2(L + W):

40 = 2(2W + 2 + W)

40 = 2(3W + 2)

20 = 3W + 2

3W = 18

W = 6

The width is 6 meters.

L = 2W + 2 = 2(6 m) + 2 m = 12 m + 2 m = 14 m

Answer: The length is 14 m.

Each coach has 50 seats and there are 1030 supporters. How many coaches are needed to take all the supporters?
alisha [4.7K]
The answer would be to divide 1030 by 50 and you would get 21 coaches not 20 because 50x20=1000 and there are 30 remainder. Therefor, you would need that extra coach with some seats left to spare. so your answer is 21 coaches
