Atriangular piece of land has one of its angle equal to 90°.the area of this land is 330sq m. if one side adjacent to the right angle is 11m what are the lengths of the other two sides

  60 m, 61 m

Step-by-step explanation:

If "a" and "b" represent the lengths of the sides adjacent to the right angle, the area is ...

  area = (1/2)ab

Filling in the given information, we can find the other side to be ...

  330 m² = (1/2)(11 m)b

  60 m = b  . . . . . . divide by the coefficient of b

Then the remaining side can be found from the Pythagorean theorem:

  c² = a² + b² = 11²  + 60² = 3721

  c = √3721 = 61 . . . meters

The lengths of the other two sides are 60 m and 61 m.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
