Answer:
The dimensions of rectangle are
the base is
the height is
Step-by-step explanation:
The question in English is
The difference between the base and the height of a rectangle is 4m. Find the dimensions of this rectangle knowing that the area is 60 m squared.
Let
b-----> the base of rectangle
h----> the height of rectangle
we know that
The area of rectangle is
![A=bh](https://tex.z-dn.net/?f=A%3Dbh)
![A=60\ m^{2}](https://tex.z-dn.net/?f=A%3D60%5C%20m%5E%7B2%7D)
so
-----> equation A
![b-h=4](https://tex.z-dn.net/?f=b-h%3D4)
-----> equation B
substitute equation B in equation A
![h^{2}+4h-60=0](https://tex.z-dn.net/?f=h%5E%7B2%7D%2B4h-60%3D0)
using a graphing tool
solve the quadratic equation
The solution is ![h=6\ m](https://tex.z-dn.net/?f=h%3D6%5C%20m)
see the attached figure
Find the value of b
