The series of numbers is adding 5 and then subtracting 2
20+5=25
25-2=23
23+5=28
28-2=26
and so on. Do you understand?
Answer:
A) 147.6 sq m
Step-by-step explanation:
Separate the pyramided out into 4 triangles and add those
3 of them (sides) will be the same
This is one half of the side, multiply by 2 to get the area of the entire side, 40 square m.
The area of all 3 sides together is 40*3 = 120 sq m
For your base, your height will be 6.9 and your base is 4
A = 13.8 sq m
multiply by 2 again for the entire base
A=27.6 sq m
Now add both
120 + 27.6
Answer:
32 units squared
Step-by-step explanation:
This is kind of a weird shape, so split it into smaller shapes, in this case two triangles and a rectangle.
Both of the triangles have a base of 8 and a height of 2. Multiply the base and the height together, then divide by 2. 8*2/2 equals 8, so the area of each triangle is 8.
For the rectangle, the length is 2, and the width is 8. Multiply the length and the width together to get 16.
Finally, add the areas of all those smaller shapes together to get the area of the whole shape, 32 units squared.
