Question

1. The length of a rectangle is 3x - 4y + 6z and the perimeter is 7x + 8y + 172, find
breadth of the rectangle.(please help me with this)​

Answer 1

Answer:

Step-by-step explanation:  Length of rectangle =3x−4y+6z

2× length =6x−8y+12z

and perimeter=7x+8y+17z=2× (length+Breadth)

So,

2× breadth = Perimeter−2× length

=(7x+8y+17z)−(6x−8y+12z)=x+5z+16y

breadth =  x+5z+16y / 2
