Answer:
The correct answer is option B. 54 ft^2
Step-by-step explanation:
Formula:-
Area of triangle
Area A = bh/2
b - Base of triangle
h - Height of triangle
To find the area of triangle
Here base b = 9 ft and height h = 12 ft
Area, A = bh/2 = (9 * 12)/2 = 54 ft^2
Therefore the area of given triangle is 54 ft^2
Answer:54sqft
A=b*h/2
A=9*12/2=54sqft
Put h = 7 to the expression 5 · (h + 3):
he would have paid 3.36
it was a three-dimensional figure
