sewing a border of ribbon onto her rectangular picnic blanket. The long side of the blanket is 70cm and the short side is 40cm.
Strike441 [17]

Answer:

220 cm

Step-by-step explanation:

We need to find the perimeter of the rectangular blanket in this case because a border is being sewn onto the blanket. The perimeter of a rectangle can be calculated by multiplying the sum of the rectangle's length and width by 2. As an algebraic expression, that would be 2(l+w), where l is the rectangle's length and w is the rectangle's width. We are given that l=70 and w=40. Therefore, 2(70+40)=2*110=220 cm of ribbon will be needed. Hope this helps!
