Find the base area $B$ of a triangular prism if side $a = 2 cm$ and length $l = 4 cm$ .

Answer

$3 cm^{2}$

Explanation

To find base area $B$ use formula:

B = \frac{3 \cdot a ^{2}}{4}

After substituting $a = 2 cm$ we have:

B = \frac{3 \cdot ( 2 cm ) ^{2}}{4}

B = \frac{3 \cdot 4 cm ^{2}}{4}

B = \frac{4 3 cm ^{2}}{4}

B = 3 cm^{2}
