Answer: 1680
Step-by-step explanation: first we have to find the area of each triangle so we do 7 times 12 then divide by 2 which equals 42. then since there are 40 tiles we multiply by 40 which will equa 1680.
You are allowed to move the decimal points before dividing with decimals because then, you will be able to divide by a whole number outside the dividend. Move the decimal point so that you are dividing by a whole number.
Answer:
b
Step-by-step explanation:
Opposite of 12 is -12
absolute value of -12 is 12
distance between 0 and -12 is 12
absolute value of 12 is 12
A
Answer:
162 m²
Step-by-step explanation:
To find the area of this composite solid, we need to find the area of each surface and sum them up.
Formula for finding area is length x width.
Area of each surface:
3 * 2 = 6
9 * 2 = 18
5 * 2 = 10
2 * 2 = 4
8 * 2 = 16
(11-2) * 3 = 27
Considering the fact that each surface appeared twice in the figure, the area of the surface will be calculated as:
(6 + 18 + 10 + 4 + 16 + 27) * 2
= 81 * 2
= 162 m²
