A flowerbed is 3 3/4 meters long and 2 meters wide. Uncle James wants to build a border around the flowerbed. The width of the border is 1/2 meter. The cost of building the border is $20 per square meter. How much does Uncle James have to pay to have the border built. 3.75+3.75+2+2=11.5. 11.5*.5= 5.75. 5.75*$20=115 am I correct
To determine the cost of building the border around the flowerbed, you correctly calculated the total length of all sides of the flowerbed as 11.5 meters.
Then, you found the width of the border by adding the width of the flowerbed (2m) with the width of the border (0.5m), giving a total width of 2.5 meters.
To find the area of the border, you multiplied the total length (11.5m) by the width of the border (2.5m). This gives you an area of 28.75 square meters.
Finally, to calculate the cost, you multiplied the area of the border (28.75 sq.m) by the cost per square meter ($20/sq.m).
Therefore, the correct calculation would be 28.75 sq.m x $20/ sq.m = $575.
So, the correct answer is Uncle James would have to pay $575 to have the border built.
First start off with this
8 x 1/2 = 4
4 x 20 = $80
your presentation of
3.75+3.75+2+2=11.5. 11.5*.5= 5.75. 5.75*$20=115
would not be acceptable to me.
besides, it makes no sense.
original length = 3.75 m
original width = 2 m
new length = (3.75 + 1) m = 4.75 m
new width = (2 + 1) m = 3 m
area including border = 4.75 x 3 m^2 = 14.25 m^2
area of flowerbed = 3.75 x 2 m^2 = 7.5 m^2
area of only the border = 14.25-7.5 or 6.75 m^2
cost = $20(6.75) = $135.00
