The length of the top of a rectangular desk is 24inches more than the width. what are the dimensions of the desk if the area of the top is 1,620 square inches?

The dimensions of the desk are

Length: 54 inches

Width: 30 inches

Step-by-step explanation:

we know that

The area of rectangle is equal to

where

L is the length

W is the width

we have

so

----> equation A

----> equation B

substitute equation B in equation A

solve for W

Solve the quadratic equation by graphing

The solution is W=30 in

see the attached figure

Find the value of L

therefore

The dimensions of the desk are

Length: 54 inches

Width: 30 inches

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of
