Answer:
use BODMAS
brackets
of
division
multiplication
addition
subtraction
or Americans would use BEDMAS I think
so it'll be 8 + 4 ÷ (-24) × (3) - 4 = 35
u can break the brackets down further
The area would be about 83.14.
You can find this by starting with the formula for the area of an equilateral triangle:
A = 
In this equation, A is the area and S is the side. So we'll just plug in the value.
A = 
A = 
A = 
A = 83.14
Hello!
The answer is: 17 ft.
Explanation:
To find this out, just divide the perimeter, and the amount of sides in a triangle, which is 3. This will only work with equilateral triangles because an equilateral triangle has all three sides the same length. Anyway, divide 51 and 3. (51 / 3 = 17) Just to make sure, you can add three 17's together, 17 + 17 + 17 = 51, the perimeter.
I hope this helped! ~Q
Answer/Step-by-step explanation:
1. The figure is composed of a triangle and a rectangle.
Area of the triangle = ½*base*height
base = 4 ft
height = 12 - 8 = 4ft
Area of triangle = ½*4*4 = 8 ft²
Area of rectangle = length * width
Length = 8 ft
Width = 4 ft
Area of rectangle = 8*4 = 32 ft²
✔️Area of the figure = 8 + 32 = 40 ft²
2. The figure is composed of a semicircle and a triangle
Area of the semicircle = ½(πr²)
radius (r) = 3 cm
π = 3
Area = ½(3*3²) = 13.5 cm²
Area of triangle = ½*base*height
base = 3*2 = 6 cm
height = 6 cm
Area = ½*6*6 = 6 cm²
✔️Area of the figure = 13.5 + 6 = 19.5 cm²
