Answer:

Explanation:
x^2=+5X=300
Let
x = the width of the rectangle
y = the length of the rectangle
we know that
the area of the rectangle is equal to
A=xy ___ equation 1
y=x+5 ___equation 2
substitute equation 2 in equation 1

------> given problem
so
the area of the rectangle is equal to

Solve the quadratic equation

we know that
The formula to solve a quadratic equation of the form
is equal to

we have

so

substitute in the formula





The solution is

Find the value of y
y=x+5
