Chapter 14.6, Problem 24HP

To determine

To calculate area of rectangle

Answer to Problem 24HP

  $-8x^2+18x$ units

Explanation of Solution

Given information:

length= $2x$

width= $9-4x$

Formula used: area of rectangle = length×breadth

Calculation:

Substituting value of length and width

Area of rectangle= $2x\times (9-4x)$

  = $18x-8x^2$

  = $-8x^2+18x$

Hence, area of rectangle is,

  $-8x^2+18x$
