Answer:
hello
Step-by-step explanation:
Aera
(3y+4) x 8
=24y+32 cm²
Perimeter
2(3y+4+8)
=2(3y+12)
=6y+24 cm
Answer:
Area: [tex]24y+32[/tex]
Perimeter: [tex]6y+24[/tex]
Step-by-step explanation:
It is given that the length of the rectangle is 3y+4 cm and the width is 8 cm.
We know that the formula for the area of a rectangle is length times width so we can make an expression to represent that and then simplify.
[tex]8(3y+4)\\[/tex]
Distribute
[tex]24y+32[/tex]
Now to find the perimeter of a rectangle the fomula is 2L+2W
[tex]2(3y+4)+2(8)\\6y+8+16\\6y+24[/tex]
