The figure of the prism is attached below.

The total surface area of the prism equals the sum of areas of two triangles and the three rectangles.

Surface Area of Prism = Area of 2 Triangles + Area of 3 Rectangles.

Area of a Triangle = 0.5 x Base x Height
Area of a Triangle = 0.5 x 3 x 4 = 6 square units

There are 3 rectangles. From the figure we can see that the bottom most rectangle has the dimensions 4 by 6. The left most rectangle has the dimensions 3 x 6 and the right most rectangle has the dimensions 5 by 6.

So, the Area of 3 rectangles will be = (4 x 6) + (3 x 6) + (5 x 6) = 72 square units

The Surface Area of the prism will be:

Surface Area = 2 (4) + 72 = 84 square units

Thus the correct answer is option A

What is the area of the sector?
xeze [42]

Area of the sector is 981.3 cm²

Step-by-step explanation:

  • Step 1: Find the area of the sector where radius = 50 cm and central angle = 45°

Area of the sector = πr² (C/360), where r is radius and C is the central angle

⇒ Area = 3.14 × 50² × (45/360)

            = 3.14 × 2500 × 1/8

            = 7850/8 = 981.3 cm²
