The area of a square postage stamp is 81/100 in 2. what is the side length of the stamp?

We have been given that area of a square postage stamp is

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

Substituting the value of area in this formula, we get

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

i believe the correct answer is b.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
