Question

What is the value of x in the rectangle with dimensions (2 1/2 + x) cm and 2 1/2 cm?

A) 0 cm
B) 1/2 cm
C) 1 cm
D) 2 cm

Answer 1

The value of x in the rectangle with dimensions (2 1/2 + x) cm and 2 1/2 cm is 0 cm (option A).

Step-by-step explanation:

To find the value of x in the rectangle with dimensions (2 1/2 + x) cm and 2 1/2 cm, we need to set up an equation. The width of the rectangle is given by (2 1/2 + x) cm, and we know that it is between 1.2 and 1.3 cm. From the information given, we can determine that the width of the rectangle is 1.25 cm.

So, (2 1/2 + x) cm = 1.25 cm. To solve for x, we can subtract 2 1/2 from both sides of the equation:

x cm = 1.25 cm - 2 1/2 cm = -1.25 cm.

Since we're measuring a length, the negative value doesn't make sense. Therefore, the value of x is 0 cm (option A).
