Question

A rectangular sheet of paper is 25/2cm long and 32/3 cm wide. Find its perimeter. *​

Answer 1

Answer:

$\frac{214}{6}$cm

Step-by-step explanation:

To find the perimeter of a rectangle, add all its sides.

Length + Length + Width + Width

$\frac{25}{2} + \frac{25}{2} + \frac{32}{3} + \frac{32}{3}$

= $\frac{50}{2} + \frac{64}{3}$

Find the LCM. It will be 6. Multiply the denominators with 2 and 3, respectively to get similar denominators, and that you can add.

 = $\frac{50}{2}\frac{X 3}{X 3}$ + $\frac{32}{3} \frac{X2}{X2}$ (the X is the multiplication sign..)

 = $\frac{150}{6}$ + $\frac{64}{6}$

Now that the denominators are both the same, you can add the fractions.

 = $\frac{214}{6}$cm ( or also 35.7cm (to 3 significant figures) or $35\frac{4}{6}$)

Answer 2

Answer:

46.3cm

Step-by-step explanation:

• perimeter is length around shape
• 25/2 multiply by 2 becoz it's got two equal sides
• 32/3 multiply by two for the other equal sides
• add answers together to give you
• 46.3cm
