Question

the area of a triangle is 36 metre square and altitude is 3 cm find the base corresponding to altitude of the triangle

Answer 1

area = 36 m² = 360000 cm²
altitude = 3 cm

area of ∆ = 1/2 × base × altitude
360000 = 1/2 × 3 × base
360000 = 3/2 × base
base = 360000 × 2/3 = 240000 cm = 2400 m

Answer 2

area of triangle=1/2×b×h
36=1/2×b×3/100m
36×2×100/3=b
2400m is base
