99cm2

Explanation:

Answer 2

Option D.

Explanation:

In this question figure of pyramid is attached below the question .

Surface area of the rectangular pyramid :

Area of the Base = Length × Width

= 10 × 2 = 20 cm²

Area of Lateral #1 =
`(1)/(2)(P)(L)`

=
`(1)/(2)(10*6.3)`

= 31.5 cm²

Area of Lateral #2 =
`(1)/(2)(8* 2)`

=
`(16)/(2)`

= 8 cm²

Surface area of the pyramid = 20 + 2(31.5) + 2(8)

= 20 + 63 + 16

= 99 cm²

Surface area of the pyramid is 99 cm²
