The area of a triangle is base times height divided by 2.
Altitude is just another word for height.
Base = 7
Height = 11
Area = 7(11)/2 = 77/2 = 38.5 square inches

area of a triangle = (1/2) * b * h where b = base and h = height
(1/2)*7*11 = 77/2 in^2

Area = (1/2) x base x height
A = (1/2) x 7 x 11 in ²
A = 38.5 in ²

1/2 * base* altitude= area
1/2*7*11=38.5 square inches
1 square inches = 0.00064516 m2
u can convert to m^2
