we are given
we can multiply -1 on both sides of second equation
we can see that
both equations becomes same
so, they are coincident............Answer
Answer:
D to C
Step-by-step explanation:
The radius is half the diameter or the center point to the edge (circumference)
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
There's an app called photomath that would be useful for these kinds of problems!
