Answer:
S.A=132
Step-by-step explanation:
A=[ x b x h]2
A= x 4 x 3 x 2 12+50+40+30=132
A=12 cm²
A=L x W
A=10 x 5=50
A=L X W
A=10 X 4=40
A=L X W
A=10 X 3=30
Imagine fractions as a pie. The bottom number is the total pieces of slices that make up the pie. The top number is how many you are served.
If there are a total of 5 pieces and you get 3 pieces of the pie, is that larger than getting 1 piece of the pie? Yes!
Answer:
Call the sister's height x. The boy is twice as tall, so that's 2x. The father is 30 cm taller than the boy, so his height is 2x + 30. The combined height is 3.8m, which is 380cm. Now you can write an equation
x + 2x + 2x + 30 = 380
collect like terms
5x = 350
x = 70
the sister is 70cm tall, the boy is 2*70 = 140 cm, and the father is 140 + 30 = 170cm
Check that the heights add up to 3.8m: 70 + 140 + 170 = 380 cm = 3.8m. Correct

They both belong to rational numbers.
What makes a number rational is its ability to be represented as a ratio of two integers. -1.875 is equal to -1875/1000. They are not natural numbers or integers because they are not whole.
