Answer:

Step-by-step explanation:
Given: Monica wants to measure the dimensions of her rectangular lawn.
If the longer side of the lawn is BC=(x + 3) feet.
If the diagonal length is AC=(x + 4) feet.
Let the shortest side of lawn is AB=y feet
The angle of rectangle is right angle.
Using diagonal, shortest and longer side to make a right angle triangle whose hypotenuse is length of diagonal.
Using Pythagoreous theorem,






We will ignore the negative value because side of rectangle can't be negative.


Divide total feet by feet in a mile:
63,756/5280 = 12.075 miles
Divide 70 minutes by 60 minutes per hour:
70/60 = 1.166666 hours( round to 1.17)
Miles per hour = total miles/ total hours:
12.075/1.17 = 10.32 miles per hour
Answer:
The answer is D.
Step-by-step explanation:
In similarity, the triangles have the same angles but different length of sides.
