When making a book cover, Anwar adds an additional 20 square inches to the surface area to allow for overlap. How many square in
e-lub [12.9K]

Answer:

234 square inches

Step-by-step explanation:

We are given that

Length of book, l=11 in

Width of book, w=8 in

Height of book, h=1in

Additional area required to overlap=20 square inches

We have to find how many square inches of paper to make  cover of one book.

We know that surface area of cuboid

S=2(lb+bh+hl)

Using the formula

Surface area of book

S=2(11\times 8+8\times 1+1\times 11)

S=214 in^2

Total paper used to make cover of one book

=Surface area of book +additional surface area

=214+20

=234in^2

Hence, Anwar will use paper to make cover of one book=234 square inches

A license plate consists of two letters followed by two digits; for example, $MP78$. Neither the digits nor the letters may be r
alex41 [277]

If in a number plate two different alphabets need to be selected then there are 650 such number plates that can be formed in such a way that the alphabets come in increasing order.

Given that a number plate can be formed using 2 alphabets which must come in increasing order.

We are required to find the number of plates that can be formed.

Number of total alphabets=26.

The number of plates will be equal to the number of ways in which two alphabets can be arranged.

Combination is the number of ways in which some combinations can be formed. It is expressed as nC_{r}=n!/r!(n-r)!

Number of license plates=26C_{1}*25C_{1}

=26*25

=650 plates

Hence If in a number plate two different alphabets need to be selected then there are 650 such number plates that can be formed in such a way that the alphabets come in increasing order.
