To compute the perimeter of a rectangle, you add the length, l , and width, w , and double this sum.

This means you can find the perimeter of a rectangle by evaluating the expression 2 (1 + w ).
Use this expression to find the perimeter of a rectangle with length 30 and width 75.
210 (A)
135 (B)
180 (C)
107 (D)

Answers

Answer 1

Answer:

210 (A)

Step-by-step explanation:

Use the formula:

P = 2(l + w)

Substitute the values and find P:

P = 2(30 +75) = 2(105) = 210

Correct choice is A

Answer 2

Answer:

given length [l]=30

width[w]=75

perimeter= 2 (l + w )=2(30+75)=210

so

answer is A.210

A bag contains 21 coins consisting of nickles and dimes. The total value of the coins is $1.70.
Write a system of equations that models this situation. How many nickels are in the bag?

Answers

Answer:

8

Step-by-step explanation:

x = nickles

y = dimes

0.05x + 0.10y = 1.70

x + y = 21

y = 21 - x

0.05x + 0.10 (21 - x) = 1.70

0.05x - 0.10x + 2.10 = 1.70

-0.05x + 2.10 = 1.70

-0.05x = -0.40

x = 8
