Question

Which expresion represents the perimeter of the rectangle above (3y-5), 2y

Answer 1

Answer: The expression represents the perimeter is 10y-10.

Step-by-step explanation:

Let the length of rectangle be 3y-5

Let the breadth of rectangle be 2y

As we know the formula for perimeter,

So,

$\text{Perimeter of rectangle }\\\\=2(L+B)\\\\=2(3y-5+2y)\\\\=2(5y-5)\\\\=10y-10$

This is the required expression which represents the perimeter of the rectangle.

Answer 2

(3y-5 + 2y)*2 = (5y-5)*2 = 10y-10
