Answer:
Area = 77ft²
Perimeter = 44 9/20 feets
Step-by-step explanation:
Area of a triangle = 1/2 * base * height
Base = 19 1/4 feets = 77/4 feets
Height = 8 feets
Area = 1/2 * 77/4 * 8
Area = (77 * 8) / 8
Area = 77 feet²
Perimeter of a triangle :
Sum of the sides
Perimeter = a + b + c
Perimeter = 19 1/4 + 10 + 15 1/5
Perimeter = 44 + (1/4 + 1/5)
Perimeter = 44 9/20
Answer:
54
Step-by-step explanation:
This can be divided into triangle ABF and trapezoid BCDE.
A = A₁ + A₂
A = ½ (10) (3) + ½ (6 + 7) (6)
A = 15 + 39
A = 54
The area is 54 square units.
{c, d, e} is common to both sets A and C.
{c, d, e} is called "the intersection of A and C."
Look up "intersection (set theory)" on the 'Net, for more info.
