Step-by-step explanation:
 1. solution,
length of rectangle A(l)=3.1units
breadth of rectangle A(b)=1units
now,
area of rectangle A=l×b
 =3.1units×1units
 =3.1 sq units
2.solution,
length of rectangle B(l)=3.1units 
breadth of rectangle B (b)=0.4units
now,
area of rectangleB=l×b 
 =3.1units×0.4units
 =1.24 sq units
3.solution,
length=3.1units
breadth=1.4units
area =lxb 
 =3.1units x 1.4units
 =4.34units
 
 
        
                    
             
        
        
        
True, because the chord connect 2 points of the circumference, but radius connect the center and a point on the circumference.

Answer:
x = 4
Step-by-step explanation:
Given y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition y = 24 when x = 6 , then
24 = 6k ( divide both sides by 6 )
4 = k
y = 4x ← equation of proportion
When y = 16, then
16 = 4x ( divide both sides by 4 )
4 = x
