Gwar [14]

Answer:

Panels produced by Plant B = 12000

Step-by-step explanation:

Let the number of panels produced by plant B be 'x'

Now, according to the given information;

⇒ 9000(\frac{10}{100} ) + x(\frac{3}{100} ) = (9000 + x)(\frac{6}{100} )

⇒ 90000 + 3x = 54000 + 6x

⇒ x = 12000

A Triangular Park ABC has sides 120 m, 80m and 50m. a gardener has to put a fence all around it and also plant grass inside. How
Vadim26 [7]

The perimeter = sum of all sides

= 120 + 80 + 50

= 250

So 250 - 3

247

Left space for gate

Now cost of fencing = Rs 20/per meter

= 247 × 20

= Rs 4,940

Now the area of the triangular park can be found using heron's formula

S = (a+b+c)/2

S = (120+80+50)/2

S = 250/2

S = 125

Now

Herons formula = √s(s-a)(s-b)(s-c)

√125(125-120)(125-80)(120-50)

√125(5)(45)(70)

√5×5×5×5×5×3×3×5×14

After Making pairs

5×5×5×3√14

375√14

Therefore 375√14m is the area of the triangular park
