For this question the answer is 2.5m (B)

You find this by: L=0.85m

W=0.4m

A rectangle had 4 sides (2 lengths and 2 widths)

So...

To find 1 length and 1 Width you do 0.85+0.4=1.25m

Now you want to find the other 2 sides (L and W)

You can do: the same method and add it to 1.25m OR...

You can do (I prefer this one): (0.85+0.4)x2=?

This is the same as 0.85+0.4=1.25

1.25x2=2.5m

You find this by: L=0.85m

W=0.4m

The surface area of a rectangular prism is this:

SA = LW + LH + LH

Here are the changes:

L --> (2/3)L

W --> 4W

H --> H/2

So, the new surface area is:

SA' = (2/3)L (4W) + (2/3)L (H/2) + 4W (H/2)

SA' = (8/3) LW + (1/3) LH + 2 WH

SA = LW + LH + LH

Here are the changes:

L --> (2/3)L

W --> 4W

H --> H/2

So, the new surface area is:

SA' = (2/3)L (4W) + (2/3)L (H/2) + 4W (H/2)

SA' = (8/3) LW + (1/3) LH + 2 WH

The basic definition of a perimeter is the boundary line of an object. For shapes and figures, this is basically the sum of the outermost sides that define the object. Since an octagon has eight sides, with each side measuring 12m, the perimeter can be obtained by multiplying 12 m by 8 sides, or in equation form:

P = 8(12)

Among the choices, this is letter B.

P = 8(12)

Among the choices, this is letter B.

QUESTION POSTED AT 18/01/2020 - 07:14 AM

**Answer:**

**Option (c) 7.6 cm is the correct answer**

**Step-by-step explanation:**

Three sides of a quadrilateral measure 2.5 cm, 1.8 cm, and 9 cm.

Perimeter of the quadrilateral is 29.9 cm

Then we have to find the length of 4th side.

Since perimeter of any quadrilateral = sum of all four sides

so by using this formula

20.9 = 13.3 + x

x = 20.9 - 13.3

x = 7.6 cm

**Option (c) 7.6 cm is the correct answer**

**Answer:**

**The radius is DE.**

**Step-by-step explanation:**

Given that

In ABC, the angle bisectors meet at point D. Point E is on AC, DE and is perpendicular to AC . Point F is the location where the perpendicular bisectors of the sides of the triangle meet.

we have to find the radius of the largest circle that can fit inside ABC.

**The incenter of the triangle is the point formed by the intersection of the triangle's 3 angle bisectors. **

Here, the angle bisectors meet at point D therefore **the incenter is point D **and the side AC is the tangent to the circle that fits inside ABC.

Hence, **the radius is DE.**
