Given :

Altitude = 9 cm

Area of triangle = 54 cm²

Base = ?

We know,

Ar. of triangle = ½ × base × height

54 cm² = ½ × 9 × height

height = 54 × 2/9

height = 6 × 2 cm

Therefore, Height = 12 cm

${\bold{\underline{\underline{Given:-}}}}$

➡Area of triangle = 54cm^2

➡Altitude = 9cm

${\bold{\underline{\underline{Find:-}}}}$

➡Base= ❓

${\bold{\underline{\underline{Solution:-}}}}$

Formula used :--

Area of triangle= 1/2 x B x H

➡ 54 =1/2 x B x 9

➡54 x 2/ 9 = B

➡B =12cm
