Answer:

255

Step-by-step explanation:

Take your rectangle first

22*10 = 220 cm^2

Now your triangle:

The base is 7cm ( 17 - 10), and the height is 10 cm (22-12)

A=10 * (7/2)

A= 35

Now add both together.

Answer: 255 cm squared

Step-by-step explanation:

the area of the rectangle is length x width. 22 x 10 = 220.

the sides of the triangle are found by subtracting the sides of the rectangle.

22 - 12 = 10 and 17 - 10 = 7.

the area of the triangle is base x height / 2. so 10 x 7 / 2 = 35.

add the area of the rectangle and the area of the triangle.

220 + 35 = 255.

What is 39.79949748 rounded to the nearest hundredth?

Rufina [12.5K]

Answer:

$Number = 39.80$

Step-by-step explanation:

Given

$Number = 39.79949748$

Required

Approximate (to the nearest 100th)

This means that, we approximate at the second digit after the decimal.

So:

i.e,

Number = 39.79 [Begin approximation] 949748

The first digit after [Begin approximation] is then approximated using the following rule:

$0 - 4 \approx 0$

$5 - 9 \approx 1\\$

Since 9 falls in $5 - 9 \approx 1\\$ category, the number becomes:

$Number = 39.[79+1]$

$Number = 39.80$
