Answer:
Well the answer is the first one 3 (5 x) and 15x
Step-by-step explanation:
Because it is the same thing as (5 x) 3. The numbers just changed the positions.
And 15x because you can multiply the first 5 times 3 and that is equal with 15 and then you put the x at the end. 15x
Two equilateral triangles, but one has sides measuring 3 cm, while the other measures 6 cm. The figures are similar, but not congruent
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
The answers that you put are right.
