In this problem, the average is already given. In order to solve for the missing length of jump rope we have the following solution:
Let x = be the total length
X = 4(112)
X = 448
Therefore,
34m + 1m + 212m = 247m
448m - 247m = 201 length of the fourth jump rope
recall in a perfect square trinomial, the middle term is the tale-tell guy, we know the middle term is the product of 2 and the two other guys without the exponent, so in this case 6x = 2*√x² * √c.


Given,
Area = 225 yd²
Base = 30 yd
Height = [To be calculated]
To find:
The height of the given triangle.
We know that, area of a triangle is:

Therefore, the require height is 15 yd.
Proof:
