What is the value of B for the following triangular prism? 5.25 cm2 56 cm2 52.5 cm2 5.6 cm2

5.25 cm²

Step-by-step explanation:

B represents the area of the triangular end.

B = bh ( b is the base and h the perpendicular height )

Here b = 28 mm = 2.8 cm ← note change from mm to cm ( divide by 10 )

and h = 3.75 cm , thus

B = × 2.8 × 3.75 = 1.4 × 3.75 = 5.25 cm²

it should be a and d. lmk if i'm wrong xd
