Mathematics

Answer:

15.5

Step-by-step explanation:

So the formula here is the square of the tangent length is equal to the product of the exterior part of the secant line and total length of the secant.

So that means we have x^2=10(14+10).

After simplifying the right hand side we have the equation is x^2=10(24) or x^2=240.

To get rid of the square on the x, we square root both sides.

x=sqrt(240)

x=15.49193338

To the nearest tenths, the answer is x=15.5

So 15.5 inches is the length of x.

If the perimeter of vectangle wall is 360 cm and its breath is 60cm. Find its length and also find the totalt cost of painting t

alexdok [17]

Answer:

Rs. 72

Step-by-step explanation:

We have 2 values here,

Perimeter of the rectangle = 360 cm
Breadth of the rectangle (b) = 60 cm.

Firstly, we must find the length of the rectangle (l).

So, according to the formula,

Perimeter = 2 (b + l)

360 = 2 (60 + l)

360 = 120 + 2l

360 - 120 = 2l

240 = 2l

120 cm = l

Now, we need to find the area of the rectangular wall & then convert it from cm² to m² as the cost of painting is given in m².

So,

Area = lb

Area = 120 × 60

Area = 7,200 cm²

Let's convert it to m² now,

7200/1000

= 7.2 m²

Given, cost of painting per m² = Rs. 10

So, the cost of painting the wall is,

10 × 7.2

= Rs. 72
