Answer:
76.9690 square units (rounded off to four decimal values)
Step-by-step explanation:
The diameter of the semicircle is 14 units
The radius of the semicircle is thus 14 ÷ 2 = 7 units
Area of a semicircle is given by: 
× π × r²
In our case, the area is = × π × 7² = 76.9690200129 square units
Or 76.9690 square units (rounded off to four decimal values)
The second number after the decimal is the hundredths place. To round to that place, you look at the number after it. In this case 6 is the hundredths place and 5 is the number after it. If the number after it is 5 or higher, the hundredths place number increases by 1, if it is less than 5 the hundredths place number doesn't change. So the answer is 8.47.

Answer:
Area= 4y^2 + 14y + 12
Perimeter = 10y + 16
Step-by-step explanation:
Area of a reactangle = length × width
= (4y+6) × (y+2)
= 4y^2 + 6y + 8y + 12
= 4y^2 + 14y + 12
Perimeter of a rectangle = 2 × (a +b)
= 2 × ( 4y + 6 + y+ 2)
= 2 × ( 5y + 8)
= 10y + 16
