Answer:

Step-by-step explanation:

You need to set up a proportion

Let x = NK

7/13 = x/56    Notice that the longest side of the small trapezoid is the denominator of the fraction  on the left. That means that the longest side of the large trapezoid must also be the denominator of that fraction on the right.

Cross multiply

13x = 7*56                Combine the right

13x = 392                 Divide by 13

x = 392/13

x = 30.15

NK = 30.15

<h3>What is geometrical figure?</h3>

Geometrical shapes are the shapes that depict the shapes of various items. Various figures have two dimensions, while others have three. Only the x and y axes are used for two-dimensional figures, whereas the x, y, and z axes are used for three-dimensional shapes.

<h3>According to the given information:</h3>

Given,

Area = 11000m²

Radius = .10m/h

We know the area of the circle:

Area = πr²

The relation between parameter:

Area = πr²

11000 = 3.14 * (0.10t)²

Dividing both side by 3.14

11000/3.14 = (3.14 * (0.10t)²)/3.14

by solving this we get:

(.10t)² = 3503.184

.10t = 59.187

dividing both side by 0.10

t  = 59.187/.10

t =  591.877

t = 592

hours did it take for oil to cover the area  = 592
