384 m²
Explanation:
Since an octogon has 8 sides, it can be split into 8 different triangles.
To find the area of one triangle, use the formula a=bh½, or area=base×height×½. The base it 12m and the height is 8m, so do 8×12=96, then divide by 2 to get 48.
Since there are 8 triangles, multiply the area of 1 triangle by 8, and 48×8=384m².
Hope this helps!
The statement is contradictory, because it is said that every member of the family gives a gift to every other member of the family. And from 10 members, there are just 2 exchanging. Anyway, maybe they are only 2 members exchanging the gifts at that point in time.
So, each member will exchange 9 gifts (that is 10 members total minus herself), and 2 members are exchanging gifts at that point, so 18 gifts are being exchanged.
So 20% of 22.58
'of' can be translateed as multiply
20% means 20 parts ouf of 100 or 20/100=2/10=0.20
so 0.2 times 22.58=4.516 or round up to
he sould leave a tip of $4.52
Answer:
Below
Step-by-step explanation:
First I found the area of the portion that extends off (if that makes sense??)
It is a triangle, so use A = bh/2
A = (2)(6) / 2
= 6 cm^2
Next I found the area of the rectangle using A = LW
A = (6)(3)
= 18 cm^2
Total area = 18 + 6
= 24 cm^2
Hope this helps! Best of luck <3
