Step-by-step explanation:
THE BASE OF A RECTANGLE IS 8 M GREATER THAN THE HEIGHT, THE AREA MEASURES 65 SQUARE METERS HOW MUCH DO THE BASE AND HEIGHT MEASURE?
Let the height of the rectangle is h.
Base = 8+h
Area of the rectangle, A = 65 m²
We need to find the base and height of the rectangle. The area of a rectangle is given by :
A = bh
So,

Neglecting negative value, h = 15 m
Base = 8+15 = 23 m
So, the base and height of the rectangle is 23 m and 15 m respectively.

Answer: 2 hours
Explanation: As Jenny left the hospital 3 hours before Kristin and was travelling at 30 km/hour she should have gotten 90 km before Kristin started driving. As Kristin was travelling at 75 km/hour she will get 45 km closer to Jenny every hour (30-75= (-45)). 45 km/90 km= 2 hours to catch up.
