A rectangle has a height of 5x and a width of x+2

Area = (5x² + 10x)unit²

perimeter = (12x + 4)unit

Step-by-step explanation:

A rectangle has a height of 5x and a width of x+2

A rectangle is a quadrilateral that is a four sided polygon with two opposite sides parallel and equal.

Area of rectangle = length x breadth

Or

= height × width

Area = 5x × x+2

Area = 5x(x + 2)

Area = (5x² + 10x)unit²

b)  perimeter of rectangle = addition of all sides

= 2( length + breadth)

Perimeter = 2 ( 5x + x + 2)

= 2(6x + 2)

Open bracket

perimeter = (12x + 4)unit
