Step-by-step explanation:
The area of the rectangle is given by ...
A = LW
A = (20 m)(14 m) = 280 m²
__
The area of the semicircle is ...
A = (1/2)πr²
A = (1/2)π(7 m)² = 24.5π m² ≈ 77 m²
__
Then the total area is ...
280 m² +77 m² = 357 m²
_____
The width of the rectangle is the diameter of the circle, which is twice its radius. The area of a semicircle is 1/2 the area of a circle.
Answer:
45
Step-by-step explanation:
According to the Question,
- Given, Some boys and girls took part in a competition. 2/5 of the competitors were boys So 3/5 of the competitors were girls.
And there were Total 135 competitors.
So, the Number of Boys are 135 × (2/5) = 54 boys
Therefore, the Number of Girls in the competition is 135-54 = 81 Girls.
Now,
- 1/3 of the boys were disqualified from the competition. So, 54× (1/3) = 18 boys Disqualified . the Remaining boys are 54-18 = 36 boys left in Competition.
- Then, The number of girls more than that of boys left in competition were 81-36 = 45
