Answer:
Use the formula for the area of a triangle:
A = BH x 1/2
Where 'B' represents the base, 'H' the height, and multiplying by 1/2 just means dividing the product of those two lengths by 2.
What we know:
- Base = 12 feet
- Height = 17 feet
Which is all we need to know, so plug these values into our formula;
A = BH x 1/2
A = 12(17) x 1/2
Now just solve:-
A = 204 x 1/2
A = 204/2
A = 102, the area of this triangle is 102 ft²!
