Answer:
perimeter= 2(4x+3) + 2(5x)
Area= (4x+3)(5x)
Step-by-step explanation:
Perimeter is the sum of total length and width. Perimeter is the outside. Like a fence.
A rectangle has two equal lengths and two equal widths.
If the length is 4x + 3, we have two of those. (4x + 3) + (4x + 3)
Which can be simplified as 2(4x+3)
If the width is 5x, we have two of those.
5x + 5x
Which can be simplified as 2(5x)
So length + length + width + width=
(4x+3) + (4x+3) + (5x) + (5x)
Simplified as
2(4x+3) + 2(5x)
Area is length multiplied by width. Area is the inside. Like the property inside the fence.
Length: 4x + 3 Multiplied by width: 5x
(4x+3) × (5x)
Properly written as (4x+3)(5x)
