Find the dimensions of a rectangle whose perimeter is 22 meters and whose area is 30 square meters

The dimensions of rectangle are 5 m x 6 m

Step-by-step explanation:

Let

x -----> the length of rectangle

y ----> the width of rectangle

we know that

The area of a rectangle is

so

-----> equation A

The perimeter of a rectangle is

so

simplify

isolate the variable y

-----> equation B

we have

-----> equation A

-----> equation B

Substitute equation B in equation A

Solve the quadratic equation by graphing

using a graphing tool

the solution is x= 5 or x=6

see the attached figure

Find out the value of y

For x=5

For x=6

therefore

The dimensions of rectangle are 5 m x 6 m
