Question

The length of a rectangle is 3x – 4y + 6z and the perimeter is 7x + 8y + 17z, find the breadth of the
rectangle.

Answer 1

Answer:

ANSWER

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 =2x+5z+16y=2x+8y+25z

Step-by-step explanation:

Answer 2

Answer:

1/2 ( x + 16y + 5z )

Step-by-step explanation:

length of a rectangle is 3x – 4y + 6z

the perimeter is 7x + 8y + 17z

find the breadth of the rectangle.

perimeter of Rectangle= 2(l+b)

perimeter of Rectangle= 2l + 2b

perimeter of Rectangle - 2l = 2b

7x + 8y + 17z -2(3x – 4y + 6z ) = 2b

7x + 8y + 17z - 6x + 8y - 12z = 2b

x + 16y + 5z = 2b

Breadth, b = 1/2 ( x + 16y + 5z )
