Answer:
A) The side is 14 cm
B) The total distance around the whoole board is 56 cm
Step-by-step explanation:
So we know its a square.
A square is all equal sides
We got the area which is 196
So we know area of a square is L*W or S^2
And since all sides are equal we can square root 196
That would give you 14
So we know each side is 14
Part B is just perimeter, there are 4 equal sides so we can just multiply 14*4 which is 56.
CHECK:
So we want to check the sides are equal
Each side is 14
and area is 196
14*14=196
So its true
<span>Let P be the cost per pound of peanuts.
Let M be the cost per pound of M&M's.
We can set up two equations to solve this question.
(1) 8P + 5M = 55.27
(2) 6P + 4M = 42.70
Let's multiply equation (1) by 3.
Let's multiply equation (2) by 4.
(1) 24P + 15M = 165.81
(2) 24P + 16M = 170.80
Let's subtract equation (1) from equation (2).
M = 4.99
Let's put M = 4.99 in equation (2) to find P.
6P + 4(4.99) = 42.70
6P = 42.70 - 19.96
6P = 22.74
P = 22.74 / 6
P = 3.79
The cost per pound of peanuts is $3.79
The cost per pound of M&M's is $4.99</span>
