The area is 132 cm.

The larger rectangle area is : 108 cm

12×9=108

The small rectangle area is : 24 cm

4×6=24

Now add:

24+108=132

It is rational and equal to 0. square root of 28 simplifies to 2 root 7, because you can take out the 4 and leave the 7 under the radical. because sq rt of 28 is 2 root 7, it's the same as the first term so it equals 0

What is the best approximation for the area of this circle?

butalik [34]

$Area =113.0ft^2$ . Correct option is D) 113.0 ft² .

<u>Step-by-step explanation:</u>

Here we have , A circle labeled with radius = 6 ft . We need to find the best approximation for the area of this circle . Let's find out:

We know that area of circle = $\pi r^2$ , We have following parameters as

$Radius = r = 6 ft\\\pi = 3.14\\Area= \pi r^2 = ?$

So , Area of circle is

⇒ $Area =\pi r^2$

⇒ $Area =(3.14) (6)^2$

⇒ $Area =(3.14) (36)^$

⇒ $Area =113.04ft^2$

On Rounding off

⇒ $Area =113.0ft^2$

Therefore , $Area =113.0ft^2$ . Correct option is D) 113.0 ft² .

A regular polygon has sides all the same length, and angles all the same measure. Find the pelmeter of the regular polygon below

Ede4ka [16]

The perimeter of the regular polygon is 70 inches

<h3>How to determine the perimeter of the regular polygon?</h3>

The sides of the regular polygon is given as:

Side = 10 in

The regular polygon has 7 sides

So, the perimeter of the polygon is calculated as:

P = Side lengths * Number of sides

This gives

P = 10 inches * 7

Evaluate

P = 70 inches

Hence, the perimeter of the regular polygon is 70 inches
