Answer:
16+24=40
Step-by-step explanation: 2x+5(y-1) when x=8 and y=5. put x where it belongs, by the 2 and do the same with y, by the -1. and then slove. 2*8= 16 , 5*5= 25-1, then add 16 and 24 together and get 40.
First, we must understand that to find the perimeter of an object you must add up the lengths of each side.
Some options are:
A square (4 sides) with sides of 4 units long.
4x4=16
A rectangle (4 sides) that is 6 units long and 2 units wide
6+2+6+2=16
An octagon (8 sides) with sides 2 units long
8x2=16
