Answer:
19s + 23
Step-by-step explanation:
P = 2(4s + 10) + s+4+19s-1
P = 8s + 20 + s + 4 + 10s - 1
P = 19s + 23
The answer is 19s +23
You add together all the sides and simplfy down.
4s+10+s+4+4s+10+10s-1
Add all the like terms
until it gets to 19s+23
20 cm
So from the problem we get that the two sides of the rctangle are 16 cm 12 cm which are base perpendicular of the right angle triangle. H = 20 cm. So the diagonal of the rectangle = 20 cm.
