Given:
length of rectangle = 4 units
Height of rectangle = 2x + 6 units
To find:
Not given, so I will find area and perimeter of rectangle. If you want the length of the diagonal of the rectangle, please ask me.
Steps:
Perimeter of rectangle = 2(L + B)
= 2( 4 + 2x + 6 )
= 2( 10 + 2x )
= 2 * 10 + 2 * 2x
= 20 + 4x units
Area of rectangle = L * B
= 4 * (2x + 6)
= 4 * 2x + 4 * 6
= 8x + 24 units²
Therefore, the perimeter of the rectangle is 20 + 4x units, and the area of the rectangle is 8x + 24 units².
