Find the scaling ratio

Perimeter of first pentagon is 12*5=60 cm

Scale factor (2nd/first)=140/60 =7/3

**Ratio of areas varies as the square of the scale factor for the lengths**

Area of second / area of first =(7/3)^2 =49/9

Area of second pentagon =**248 *(49/9) cm^2**

Finish the calculation.

The two pentagons are similar. If k is the scale factor for the lengths, the ratio of the areas is k^2.

Pent 1 side =12 cm

Pent 2 side =140/5 =28 cm

Scale factor (larger over smaller) is k=28/12=7/3

Area of Pent_2= (49/9)*Area of Pent_1

Your answer should be C.

Pent 1 side =12 cm

Pent 2 side =140/5 =28 cm

Scale factor (larger over smaller) is k=28/12=7/3

Area of Pent_2= (49/9)*Area of Pent_1

Your answer should be C.

Go to armstrong installation guides on the web, they should give you hints on things like cutting around door jambs etc. And yes you can score and snap. Make sure you get a heavy score into it though

Multiply 9ft by 2ft by 2ft to get 36 cubic feet. One foot is exactly 0.3048 meters so one cubic foot is about 0.0283 cubic meters. Multiply that by 36 to get about 1.019 cubic meters.

If it is a cube, length, breadth, and height are all equal. If volume (not the area) is 216 cm^3 then

V=s^3 where s is the measure of a side

s=CUBIC ROOT (216)=6

**s= 6 cm**

V=s^3 where s is the measure of a side

s=CUBIC ROOT (216)=6

The diameter of the circle is the diagonal of the rectangle use Pythagoras this rectangle is a made from two 3,4,5 triangles, so the diameter is 5cm, the radius will be 2.5cm don't forget the BODMAS ordering rule (Brackets of Division Multiplication Addition and Subtraction) Also rounding to 2 decimal places. This solution is based on all four corners of the rectangle touching the circumference of the circle.

Area of a circle is P (22/7) i x Radius (squared ^2) ====> 22/7 x 2.5cm ^ 2 ====> 22/7 x 6.25cm

TOTAL AREA of CIRCLE = 19.64 cm^2

Area of the rectangle is length x width ====> 4 cm x 3 cm

TOTAL AREA of RECTANGLE = 12 cm ^2

The remaining portion is the circle area minus the rectangle 19.64-12 = 7.64 cm^2

It is solved by writing an equation

If the shorter piece is y cm, then the the longer piece would be 4y which is four times the shorter length. The total of these 2 together is 2meters or 200 cm, Now write the equation (2 pieces together is 200cm)

y + 4y = 200

5y =200

y =40

Since we have taken the lengh of shorter piece as y,

Shorter piece=40 cm OR 0.4m

Longer piece =160cm OR 1.6m

I have written the steps in detail for you to understand the process

Good luck
