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

Mia wants to borrow £6000 and repay it, with interest, after two years. she sees two offers for loans: offer 1 compound interest
AURORKA [14]

Answer:

she is wrong, offer 2 results in lower interests

Step-by-step explanation:

total amount paid if offer 1 is accepted:

$6,000 x (1 + 3%)² = $6,000 x 1.0609 = $6,365.40

she will pay $365.40 in interests

total amount paid if offer 2 is accepted:

($6,000 x 1.01) x 1.05 = $6,060 x 1.05 = $6,363

she will pay $363 in interests

Compounding interest refers to interest that earns more interest itself, e.g. in the first offer, the $180 of interests charged for the first year will earn $5.40 in extra interests. While offer 2 only charges $60 in interests during the first year which will in turn earn $3 of interests. The difference between both offers is that interest charges in offer 1 earn more interests than the interest in offer 2 = $5.40 - $3 = $2.40

The figure below shows a rectangular lawn. 23ft 14ft (a) Use the calculator to find the perimeter and area of the lawn. Make sur
tamaranim1 [39]

The area and perimeter of the lawn will be 322 square feet and 74 feet. If the lawn will be mowed. Then the area will be used. If the lawn will be surrounded by a rope. Then the perimeter will be used.

<h3>What is a rectangle?</h3>

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

The figure below shows a rectangular lawn.

Then the area of the rectangle will be

Area = 23 × 14

Area = 322 square feet

Then the perimeter of the rectangle will be

Perimeter = 2 (23 + 14)

Perimeter = 2 × 37

Perimeter = 74 feet

If the lawn will be mowed. Then the area will be used.

If the lawn will be surrounded by a rope. Then the perimeter will be used.

More about the rectangle link is given below.
