Answer:
3x+4x+5x=36
12x=36
x=36/12
x=3
3x=3 into 3=9
4x=4 into 3=12
5x=5 into 3=15
Equation
A = (b1 + b2)*h /2
Givens
b1 = 5 feet
b2 = 7 feet
h = 3 feet
Sub and solve
Area = (5 + 7)*3/2
Area = 12*3/2
Area = 36/2
Area = 18 Square feet.
2/2 = 1
Step-by-step explanation:
y2 - y1 4 - 2 2 Equals 1
x2 - x1 8 - 6 2
P = ( 4y + 6 inches) + ( 8y - B ) inches + ( 5y + 3 ) inches
Formula of Perimeter of triangle is = Sum of all sides.
P = A + B + C
