202 ]

A) 1249.5 sq cm
B) 162.75 sq cm
C) 105 sq cm
D) 38.75 sq cm

Answer 1

A = 105 cm²

Explanation:

The area (A) of the trapezoid is calculated as

A =
`(1)/(2)` [ (b₁ + b₂)h ]

where h is the height and b₁, b₂ the parallel bases

Here h = 5 , b₁ = 24 and b₂ = 18 , then

A =
`(1)/(2)` [ (24 + 18)5 ]

=
`(1)/(2)` (42 × 5)

=
`(1)/(2)` × 210

= 105 cm²
