a schools 430 square meter rooftop solar panel generates about 1100 kWh of electricity each month.what might be the panels dimensions? Use one dimension that is not a whole number.

Answers

Answer 1

Answer: Since area is length x width which is as said the squared meter or area of the rooftop. TO get the dimensions we just have to square out 430 m2.

Thus, a2 = 430
sq of a = 20.736.

I hope this helps.

The width of a rectangular block of land is 2/7 of its length. If it’s perimeter is 252m, find it’s length.

Answers

The length of the rectangular block of land is 98 m.

What is the perimeter of the rectangular block?

The perimeter of the rectangular block is given by following formula;

$\rm Perimeter \ of \ rectangular \ block= 2(Length + Width)\n\n$

Let l is the length of a rectangular block of land and w is the width of a rectangular block of land.

The width of a rectangular block of land is 2/7 of its length. If it’s perimeter is 252m, find it’s length.

The width of a rectangular block of land is 2/7 of its length.

w = (2/7) l

The width of the rectangular block of land is;

$\rm Perimeter \ of \ rectangular \ block= 2(Length + Width)\n\n 252=2(l+w)\n\n(252)/(2)=(2)/(7)l+l\n\n126= (2l+7l)/(7)\n\n 126= (9l)/(7)\n \n 9l =126* 7\n\n\rm 9l =882\n\n l =(882)/(9)\n\n l=98$

The width of the rectangular block of land is;

$\rm l = (2/7) w \n\nl =(2)/(7) * 98\n\nl=2 * 1 4\n\nl =28$

Hence, the length of the rectangular block of land is 98 m.

Answer:

Step-by-step explanation:

the perimeter is : p = 2(x+y)..... x : width y : length

you have the system ; 2(x+y) = 252.......(1)

x = (2/7) y ...........(2)

y > x ....(3)

Substitute x = (2/7) y into (1) and simplifiy and solve for y :

(2/7) y + y = 126

(2y+7y)/7 = 126

9y = 882

y = 98 m ( the length )
