Answer:
Step-by-step explanation:
Answer:
This entry deals with the congruence of polygons in general. Congruent triangles are discussed in more depth in Congruent Triangles. Polygons are congruent if they are equal in all respects: 1. Same number of sides 2. All corresponding sides are the same length
Step-by-step explanation:
It should be half antifreeze and then half water because you have to mix together
We have to assume that the pentagon shape is regular so that all sides have equal length. The lateral area is the sum of the areas of 5 triangles, all with the same base length and height.
.. lateral area = 5*(1/2)*(3 cm)*(9 cm) = 67.5 cm^2
.. base area = given as 15.5 cm^2
Total area = lateral area +base area = (67.5 +15.5) cm^2 = 83 cm^2.
