A square has an area of 100 square meters.<br> What is the perimeter of the square?
LiRa [457]

Answer:

40 square meters

Step-by-step explanation:

Perimeter means to add up all sides.

area means one side times one side

10 times 10 makes 100 so i am guessing each side is 10

10 + 10 + 10 + 10 = 40

((2t+10) / 2) + ((3t-15) / 2) + (3s) = 180 
((2t+10) / 2) + ((3t-15) / 2) + (4r) = 180
((2t+10) / 2) + ((3t-15) / 2) + (3s) = ((2t+10) / 2) + ((3t-15) / 2) + (4r) 
(2t+10) = (3t-15)   t=25
2*25+10= 60  ,   3*25-15=60
60+60= 120 ,   This rectangle has a total of 360 degrees 
360 - 120 = 240
240/2 =120
120/ 4 = 30  ,  120/3 = 40
r=30    s=40
