let "L" represent the length of the rectangle
let "W" represent the width of the rectangle
Area of the rectangle = LW
68= LW --------eqn 1
Area of a square = L/2 ×L/2
34= L^2/4
136=L^2
L= 11.67
From eqn 1 , W=68/L
W=68/11.6619
W=5.83
Answer:
w = p/2 - l
Step-by-step explanation:
When a question asks to be solved by a variable it means to get that variable on one side.
To do this lets first divide each side by 2 making the equation now ...
(l + w) = p/2
Now all we have to do is subtract l on both sides. Now we know that
w = p/2 - l
A+b=13
a-b=7
add the two equations using system of equations
2a=20
a=10
10+b=13
b=3
$32.58
Explanation
108.6 x 1.2 = 130.32
130.32/4 = $32.58
