Question

T he area of a square postage stamp is 81/100 in 2. What is the side length of the stamp?

Answer 1

We have been given that area of a square postage stamp is $\frac{81}{100} \text{ in}^2$

We have to find the side length of the stamp. In order to find the same, we use the formula for area of a square.

The area of a square with side length 'a' is given by

$A=a^2$

Substituting the value of area in this formula, we get

$\frac{81}{100} = a^2\\ \\ a=\frac{9}{10}$

Therefore, the side length of the stamp is given by 9/10 inches.
