Question

Q5. Find the perimetre of a rectangle whose length is -6y+3x and breadth is 7y - 2x.

Answer 1

Answer:

2y + 2x

Step-by-step explanation:

perimeter of rectangle = 2(l+b)

                                       =2(-6y+3x+7y-2x)

                                       =2({7y - 6y} + {3x - 2x

                                       =2(y + x)

                                       =2y + 2x

hope this helps you

Answer 2

2y+2x

Step-by-step explanation:

Length= -6y+3x

Breadth= 7y-2x

Perimeter= 2×(L+B)

$2 \times ( - 6y + 3x + 7y - 2x)$

Collect like terms

$2 \times ( - 6y + 7y + 3x - 2x)$

$2 \times y + x$

$= 2y + 2x$
