The perimeter is 18 meters
Answer:
(4, -2)
Step-by-step explanation:
When rotating a point 180° about the origin, the coordinates of the image are the negatives of the coordinates of the preimage.
You go to the y axis and go to +5, then the slope is the number in from if x. it has a one in front and under it so 1/1. Which mean up one over one. you go to the +(0,5) first point, on the line go up +1 and over to the right +1. that's your second point. (1,6) is your second point
Triangles have many special properties that other polygons do not have. Some examples are the Pythagorean Theorem for right triangles, herons formula, and triangles having it's own study of math being Trigonometry.
Area of the triangle = (1/2)*base* height = (1/2)*3*6 = 9 sm²
We have 4 triangles like this one ,
so area of 4 triangles = 9*4 = 36 cm².
Area of the square = 3*3 = 9 cm²
Surface area here means area all triangles + area of the square =36 +9 =
= 45 cm ²
Answer is 45 cm².
