Question

The area of triangular billboard is 3.125 sq. m . if it's base is 2.5 m long .what is the height​

Answer 1

Answer:

h = 2.5 m

Step-by-step explanation:

Area = 3.125 m²,  Base = 2.5 m.

∴ 1/2 * base * height = Area of Triangle

⇒  1/2 * 2.5 * h = 3.125

⇒ h = 3.125 * 2 / 2.5

⇒ h = 6.25/2.5

⇒ h = 2.5 m

Therefore,

height = 2.5 m

Hope it helps!

Answer 2

$\sf {Area\ of\ a\ triangle = \frac {1}{2}\times b\times h}\\\\\sf {3.125 m^{2}= \frac {1}{2}\times 2.5\times h}\\\\\sf {6.3\ m^{2} = 2.5\times h}\\\\\sf {h = \frac{6.3}{2.5}}\\\\\sf {h = 2.52\ m}$
