Question

1) Area of a triangle is 600 square unit. If
base of the triangle is thrice its height, then
what is base of triangle? ​

Answer 1

The height be X unit

base be 3x

aera of triangle is 600unit ²

$\frac{1}{2} \times base \times hieght = area \: of \: triangle \\ \frac{1}{2} \times 3x \times x = 600 \\ 3x {}^{2} = 600 \times 2 \\ x = \sqrt{ \frac{600 \times 2}{3} } \\ x = 20 \: unit$

the height is 20 unit

the base is 60 unit
