The length of a rectangle is 2x-7 and the width is 3x+5. Describe the step you would need to take to find the area of the rectan
Kruka [31]

Answer:

A= 6x^2-11x-35

Step-by-step explanation:

Given data

Length=  2x-7

Width= 3x+5.

Area= L*W

substitute

A= (2x-7)* (3x+5)

Open bracket

A= 6x^2+10x-21x-35

collect like terms

A= 6x^2-11x-35

Hence the area is

A= 6x^2-11x-35
