Bruno uses a piece of wrapping paper with dimensions 1 and 1/4 feet by 3 feet to wrap a gift. What is the total area of the paper used to wrap the gift?
Area is determined by using the formula A=lw Area= Length x Width
A= 1 1/4 x 3 convert to an improper fraction
A= 5/4 x 3/1 multiply
A=15/4 divide
A=3 3/4 square feet
Answer: \(A=3\dfrac{3}{4}\ ft^2\)
Step-by-step explanation:
Given: The dimensions of the wrapping paper :
\(1\text{ and}\dfrac{1}{4}\text{ feet }\text{ by 3 feet}\\\\\text{i.e }1+\dfrac{1}{4}\text{ feet }\text{ by 3 feet}\\\\\text{i.e }\dfrac{5}{4}\text{ feet }\text{ by 3 feet}\)
Now, we know that the area of a rectangle is given by :-
\(A=length*width\)
Now, the area of the wrapping paper is given by :-
\(A=\dfrac{5}{4}\times3=\dfrac{15}{4}=3\dfrac{3}{4}\ ft^2\)
