Question

Find the area of the trapezoid.

365 in2

307.5 in2

615 in2

182.5 in2

Answer 1

`A=(a+b)/(2)\cdot h\\\\a=29.2\ in.\\b=20\ in.\\h=12.5\ in.\\\\subtitute\\\\A=(29.2+20)/(2)\cdot12.5=(49.2)/(2)\cdot12.5=24.6\cdot12.5=307.5\ (in.^2)`

Answer 2

Answer:
`307.5\ in.^2`

Explanation:

The area of trapezoid is given by :-

`\text{Area}=(1)/(2)(a+b)h`, where a and b area the bases and h is height of the trapezoid.

Given: The length of the bases are 20 in. and 29.2 in. cm.

The height of the trapezoid = 12.5 in.

Now, the area of a trapezoid will be:-

`\text{Area}=(1)/(2)(20+29.2)(12.5)\\\\\Rightarrow\text{Area}=307.5\ in.^2`

Hence, the area of a trapezoid =
`307.5\ in.^2`
