Area of the heart is 178.5 cm² and Perimeter is 51.4 cm
Step-by-step explanation:
Total area of heart = Area of the square + 2 × area of the semi circle
Calculate the area of the square where side = 10 cm
⇒ Area of the square = side² = 10² = 100 cm²
Calculate the area of the 2 semicircles where radius = 10/2 = 5 cm
⇒ Area of the semicircle = 1/2 × π × r²
⇒ Area of the 2 semicircles = 2 × 1/2 × π × r² = 3.14 × 5² = 78.5 cm²
⇒ Total area of the heart = 100 + 78.5 = 178.5 cm²
Calculate the perimeter of the heart = length of 2 sides of the square + 2 × perimeter of the semicircle (since there are 2 semicircles)
⇒ Perimeter = 10 + 10 + 2 × π × r (since perimeter of semicircle = πr)
⇒ Perimeter = 20 + 2 × 3.14 × 5 = 20 + 31.4 = 51.4 cm
Answer:
P = 16 inches
A = 15 square inches
Step-by-step explanation:
The rectangle has a length from (2,3) to (2,8) which is a vertical distance of 5 units since 8-3=5. The rectangle has a width of (2,8) to (5,8) which is a horizontal distance of 3 units since 5-2 =3
This means the rectangle is 5 units by 3 units.
The perimeter of a rectangle is equal to P = 2b+2h where b=base and h=height. Here the base is 5 units and the height is 3 units.
P = 2*5 + 2*3
P = 10 + 6
P = 16 inches
The area of a rectangle is A = b*h. Substitute b=5 and h=3.
A= 5*3
A = 15 square inches
