To find the total area of the octagon you can find the area of the rectangle that is created by the entire figure and subtract the areas of the four congruent right triangles.
(10 cm x 6 cm) - [4(1/2 x 2 x 2)]
60 cm² -8 cm² = 52 cm²
The total area of the octagon is 52 cm².
Answer:
(7, 8)
Step-by-step explanation:
Midpoint Formula: 
Simply set our midpoint and given point equal into a formula to find the other endpoint:
4 = (1 + x)/2
8 = 1 + x
x = 7
6 = (4 + y)/2
12 = 4 + y
y = 8
The answers are:
A) right triangle
B) right triangle
C) right triangle
Sry I really don’t know I would help but it got me confused
Answer:
The 1st & 2nd option
Step-by-step explanation:
Ans1: 16/3
Ans2: 30
Ans3: 11/7×surd6
Ans4: 2/3×surd11
Rational number is a number that can be expressed in ratio (quotient)
It can be expressed in the form of repeating or terminating decimal
Example:
16/3 is equal to
5.3333333333....(repeating decimal)
thus it is a rational number
1/4 is equal to
0.25 (terminating decimal)
thus it is a rational number
