What is the area, in square units, of trapezoid ABCD shown below?

SOVA2 [1]

Given:

Trapezoid with bases 10 and 20, and height of the trapezoid is 6.

To find:

The area of the trapezoid.

Solution:

We know that the area of a trapezoid is:

$A=\dfrac{1}{2}h(b_1+b_2)$

Where, h is the height of the trapezoid and $b_1,b_2$ are bases of the trapezoid.

Putting $h=6, b_1=10,b_2=20$ in the above formula, we get

$A=\dfrac{1}{2}(6)(10+20)$

$A=3(30)$

$A=90$

The area of the trapezoid is 90 sq units. Therefore, the correct option is A.

Serjik [45]

Answer:

Step-by-step explanation:

$(h+k)(x)=h(x)+k(x)\\\\\bold{METHOD\ 1:}\\\\k(x)=x-2,\ h(x)=x^2+1\\\\(k+h)(2)=h(2)+k(2)\\\\\text{Calculate}\ h(2)\ \text{and}\ k(2).\\\text{Put}\ x=2\ \text{to the equations of the functions}\\\\h(2)=2^2+1=4+1=5\\k(2)=2-2=0\\\\\text\\\\\text{Substitute:}\\\\(h+k)(2)=5+0=5$

$\bold{METHOD\ 2:}\\\\k(x)=x-2,\ h(x)=x^2+1\\\\(h+k)(x)=h(x)+k(x)=(x^2+1)+(x-2)=x^2+x-1\\\\(h+k)(2)-\text{put}\ x=2\\\\(h+k)(2)=2^2+2-1=4+2-1=6-1=5$
