The length of the rectangle is 30 m
The width of the rectangle is 20 m
The sidewalk is 3m wide on all sides, so
length of sidewalk = 30+6 =36 m
Width of sidewalk = 20+6 = 26 m
Area of rectangle =
Area of rectangle =
Area of rectangle including sidewalk =
Hence, area of sidewalk alone = area of rectangle with sidewalk - area of rectangle
Surface Area = m²
Answer:
Step-by-step explanation:
We know that PEMDAS is a shortened acronym for the order in which we do operations in an expression, which is as following in the correct order:
Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.
Now your question asks you to solve the expression using PEMDAS, however that is what we would do regardless as <em>in algebra </em>PEMDAS is always in effect.
Lets break it down!
Simple enough! We just do the respective operations inside the parenthesis first (as per pemdas), which after completion yields us
Since x is undefined and the expression is completely simplified, there is nothing more we can do.
