Question

When 6 is subtracted from the length and 3 is added to the breadth of the rectangle, the perimeter becomes 24 . Write the mathematical form of the statement, using variables x and y *
2 points
A. x+y=12
B. x-y=12
C. x+y=15
D. x-y=15​

Answer 1

Answer:

x + y = 15

Step-by-step explanation:

Let length be x and breadth be y.

Perimeter of rectangle = 2x+2y

According to Condition,

2(x-6) + 2(3+y)= 24

2x - 12 + 6 + 2y = 24

2x + 2y - 6 = 24

2x + 2y = 24 + 6

2x + 2y = 30

x + y = 30÷2

x + y = 15
