Question

if the area of triangle is 43.68 cm and its base is 11.2 cm find its height

Answer 1

$area \: of \: a \: triangle = \frac{1}{2} \times base \times height \\ \\ given \: base = 11.2cm \\ \\ and \: area = 43.68cm {}^{2} \\ \\ therefore \\ \\ 43.68 = \frac{1}{2} \times 11.2 \times height \\ \\ height = \frac{43.68 \times 2}{11.2} \\ \\ = \frac{4368 \times 2}{1120} \\ \\ = 7.8cm$
hope it helps...

Answer 2

Area of the triangle = 43.68cm

Base= 11.2cm

Height = ?

Area of triangle for height = h=2 x A/B

                                        = 2 x 43.68/11.2

                                        = 87.36/11.2

                                        = 7.8 cm

height = 7.8cm

I hope it is right !
