Answer:
Step-by-step explanation: L= length w= width p= perimeter
L=3W p=55CM
P. of rectangle= 2(l+w)=55cm
L+w= 55/2= 27.5 cm
3w+w=27.5cm
4w=27.5cm
w=27.5/4=6.875cm w=6.875cm L= 3w=6.875*3=20.625cm
Answer:
The distance between A and B is 13.6
Step-by-step explanation:
Distance formula=√(x2-x1)²+(y2-y1)²
Where
x1=-7
x2=6
y1=-1
y2=-5
Putting in the formula
Distance=√(6+7)²+(-5+1)²
D=√(13)²+(-4)²
D=√169+16
D=√185
D=13.6
