What is the area of a rectangle that measures 9cm by 81mm?

1 answer:

3 0

Well, a Centimeter is 10 times bigger than a Milimeter.

So we can convert 9cm by multiplying it by 10

9 × 10= 90mm

SInce we know the length and width of the rectangle, we can now find the area of it, or "the space inside".

Area = length × width

Area = 90mm × 81mm
Area = 7290mm

Answer:

x = 13

Step-by-step explanation:

The sum of the exterior angles of a 4 sided polygon is 360

139+ 6x+9x+2x = 360

Combine like terms

139+17x=360

Subtract 139 from each side

17x = 360-139

17x = 221

Divide each side by 17

17x/17 = 221/17

x = 13

Total Number of candies = 700

To find:

The ratio of candies to chocolate bars = ?

Solution:

First of all, let us discuss the method to find the ratio of any two quantities.

Suppose, we need to find the ratio of two numbers $p$ and $q$ .

Then to find the ratio $p:q$ , we need to divide p by q and represent it in the simplest form $\frac{a}{b}$ such that a and b can not be divided further.
