Step-by-step explanation:
Perimeter of the parallelogram =2(l+b)
Length =3x and Breadth = 2x
So,
2(3x+2x)=70cm
2*5x=70cm
5x=70 divided by 2,35
5x=35
x= 35 divided by 5, 7
X=7cm.
Length =3x=3*7=21cm
Breadth =2x=2*7=14cm

Answer:
x = c - a / -b
Step-by-step explanation:
a - bx = c
-a -a
-bx = c - a
divide -b
x = c - a / -b
<h3>
Answer: B) 10.3</h3>
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(20) = x/11
11*cos(20) = x
x = 11*cos(20)
x = 10.336618828645
x = 10.3
