Question

Please help me with the question below (also please explain).

Answer 1

EXPLANATION :

We will calculate the areas of each face.

Front :

A triangle with a base of 6 and a height of 4

The area is :

`\begin{gathered} A=(1)/(2)bh \\ \\ A=(1)/(2)(6)(4)=12\text{ }cm^2 \end{gathered}`

Back :

Same face with the front, so the area is also 12 cm^2

Right :

The right side is a 5 x 3 rectangle.

The area is 5 x 3 = 15 cm^2

Left :

The left side is the same as the right side, so the area is also 15 cm^2

The total area is 12 + 12 + 15 + 15 = 54 cm^2
