The altitude will be the geometric mean of the lengths, so

. The smaller leg is the hypotenuse of a right triangle sides 4 and

so the usual trig cliche, hypotenuse 8.
Answer: 8
The answer should be 6z + 54 but I’m not completely positive.
Area of a triangle= bh/2b=4in h=8in8x4/2=16in
there are 4 triangles
4x16=64
area of a rectangle=bh
4x4=16
64+16=80in^2
This problem requires the Pythagorean therom.
The distance between them is 7.
Since the distance between them is one more mile than ray's distance from home ray is 6 miles from home.
So rosa is 
So rosa is
miles away from home.
Rosa is about 3.6 miles from home.
