Perimeter is the distance around an object / shape. Area is the amount of space within a 2 dimensional surface. For example the perimeter of a square would be the lengths of each side added together while the area would be how much space inside of it that it occupies. Area is measured in units squared, while perimeter is left in just units. In other words if the unit ( measurements ) are conducted in cm, then the area would be put in cm^2. The perimeter would just remain in cm.
Hello there!
28 recipes .......> 100%

Cross multiply
28x = 15*100
28x = 1500
x= 1500/28
x ≈ 53.5%

Answer:
99
Step-by-step explanation:
(b)(c) = 21
SInce there are 2 triangles with an area of 21, multiply that by 2 and divide it by 1/2.
(c)(a) = 39
Do the same thing
(a)(c) = 39
add everything up
21 + 39 = 60
60 + 39 = 99
Hope this helps!
