let the ratio be 3x and 4x
3x+4x=96
7x=76
x=76/7
x=10.85
base=10.85×3=32.55
height=10.85×4=43.40
3x+4x=96
7x=76
x=76/7
x=10.85
base=10.85×3=32.55
height=10.85×4=43.40

Question
The base and height of at triangle are in the ratio 3:4 and its area is 96 sq.m . find its base and height
Answer base = 3×4 = 12cm and height = 4×4 = 16 cm
Solution
Let the base be 3x
Let the height be 4x
Area of triangle, A = ½ × base × altitude = 96 m²
96 = ½ × base × ¼ base
96 = 6x²
x² = 16 or x = 4
base = 3×4 = 12cm and
height = 4×4 = 16 cm
