elana is using wrapping paper to cover aboard. each piece of paper is 2/5 yards long and 1/4 yard wide. elana uses 4 pieces of wrapping paper to cover the entire board. what is the total area in square feet, of the board? show your work .

a) 1.8

b) 3.6

Step-by-step explanation:

Conversion and calculation of areas

The area of a rectangle is A=wh, where w is the width and h is the height. There are 3 feet in one yard

a)

We are told Kalie put 6 stickers, each one of 1/2 centimeters (0.5 cm) wide by 3/5 (0.6 cm) centimeter long. The area of one sticker is

A=(0.5)(0.6)=0.3

Assuming there is no overlapping, the 6 stickers have a total area

6*0.3 =1.8

b)

Each of Elana's wrapping papers measures 2/5 yards long and 1/4 yard wide. Converting them to feet we have

long=2/5*3=1.2 feet

wide=1/4*3=0.75 feet

Area of each paper=1.2 feet*0.75 feet=0.9

Area of the entire board, assuming no overlapping and no space left uncovered=4*0.9

Area of board=3.6
