The answer is A because 5 on 2 sides would equal 10 leaving 40 left dividing it by 2 which is 20.

General formula of the perimeter is
p = 2l + 2w

Given from the question
p = 50
l = 5

Asked from the question
w?

Solution
p = 2l + 2w
2w + 2l = p

Input the numbers to the equation above
2w + 2l = p
2w + 2(5) = 50
2w + 10 = 50
2w = 50 - 10
2w = 40
w = 40/2
w = 20

Each of the other sides is 20 inches

B = 3m + 2p<br> Work out the value of p when B= 2 and m = 5
GarryVolchara [31]

This is called a "substitution problem" is where you have variable that have defined values and plug them in value calculate the expression.

B = 3m + 2p # Starting equation

2 = (3)(5) + 2p # Substitution

2 = 15 + 2p # Multiplication

-13 = 2p # Subtract 15 from both sides

\frac{-13}{2} = p # Divide both sides from 2

p = \frac{-13}{2} # Use the reflexive property of equality

Hope this helps!
