Answer:
Base of the triangle = 21 cm
Altitude of the triangle = 28 cm
Step-by-step explanation:
Let the base and altitude be 3x and 4x respectively,
Area of the triangle = 1/2 bh
=1/2(3x)(4x)
=12x²/2
=6x²
It is given that area of the triangle is 294 cm²
6x²=294
x² = 294/6
x² = 49
x = 7
Base = 3x = 3 × 7 = 21 cm
Altitude = 4x = 4 × 7 = 28 cm
