A 68 cm banner was joined to one end of another banner that was 55 cm long. The join was 3
cm wide. What was the length of the new banner formed?
clearly, that would be the sum of the lengths of all the parts:
68+3+55 = 126 cm
To find the length of the new banner formed, you need to add the lengths of the two original banners and subtract the width of the join.
The length of the first banner is 68 cm.
The length of the second banner is 55 cm.
The width of the join is 3 cm.
To find the length of the new banner formed:
New length = length of first banner + length of second banner - width of the join
= 68 cm + 55 cm - 3 cm
= 123 cm - 3 cm
= 120 cm
Therefore, the length of the new banner formed is 120 cm.
To find the length of the new banner formed, we need to add the lengths of the two original banners and subtract the width of the join.
We are given that the first banner is 68 cm long, the second banner is 55 cm long, and the join is 3 cm wide.
To find the length of the new banner, we can use the formula:
Length of new banner = Length of first banner + Length of second banner - Width of join
Let's substitute the values into the formula:
Length of new banner = 68 cm + 55 cm - 3 cm
Now we can simplify the expression:
Length of new banner = 123 cm - 3 cm
Length of new banner = 120 cm
Therefore, the length of the new banner formed is 120 cm.
