.
Answer:
C) 100 m^2
Step-by-step explanation:
Area of a trapezoid= h*[(b1+b2)/2]
h=10
b1=8
b2=12
Therefore:
A=10*[(8+12)/2]
A=10*(20/2)
A=10*10
A=100
So the area of the trapezoid is 100 m^2
Answer:
300
Step-by-step explanation:
Sum the parts of the ratio, 3 + 4 = 7 parts
Divide the total by 7 to find the value of one part of the ratio.
700 ÷ 7 = 100 ← value of 1 part of the ratio, thus
3 parts = 3 × 100 = 300 ← number of girls
4 parts = 4 × 100 = 400 ← number of boys
