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!

Find the distance between these points. r(-1, 0), s(8, 6)1-√(26)2-√(85)3-3√(13)
bixtya [17]
Distance between two points, d, is given by
d= \sqrt{ ( x_{2} - x_{1}) ^{2} + (y_{2} - y_{1}) ^{2} }

where: (x1, y1) = (-1, 0) and (x2, y2) = (8, 6)
d= 
\sqrt{ ( 8 - (-1)) ^{2} + (6 - 0) ^{2} } \\ d= \sqrt{ (9)^{2} + 6^{2} }  
\\ d= \sqrt{81+36}  \\ d= \sqrt{117}  \\ d=10.8 \ units
