Answer 1

126 square units

Explanation:

Area of section 1 is 8 square units which is triangle and,

Area of triangle is =
`(1)/(2)* b* h`

b= 2 units and height =8 units

So,

Area of section 1 =
`(1)/(2)* 2* 8=8 \quad\text{ square units}`

Same Area is of section 2 which is also a triangle and has same base and height.

So,

Area of Section 2 =
`(1)/(2)* 2* 8=8 \quad\text{ square units}`

Now the Area of section 3 which is square with side of 10 units

So,

Area of section 3 =
`a^(2) =10*10=100\quad \text{square units}`

Total Area of Trapezoid =
`8+8+100=126 \quad \text{square units}`
