Question

A stamp is 7/8 inches wide by 3/4 inches long. If Henry puts 3 stamps on an envelope, what is the total area, in square units, of his stamps?**

Answer 1

`\bold{(63)/(32)\ sq\ inches}`

Explanation:

Given that:

Width of stamp =
`(7)/(8)` inches

Length of stamp =
`(3)/(4)` inches

It is well known that a stamp is in the form of a rectangular shape.

Area of a rectangular shape is given by the following formula:

`Area = Width* Length`

Also, there are 3 identical stamps on the envelop, therefore we need to find the area of one stamp and then multiply it with 3 to find the required area.

Required area:

`3* (7)/(8)* (3)/(4)\\\Rightarrow \bold{(63)/(32)\ sq\ inches}`
