-----------

Before, finding the answer. Let's find out on how we can find the answer.

• To find the Area of the Trapezoid we must use the formula of :

$\sf \dfrac{a + b}{2} \times h$

• Where, we must first add Both the base and multiply it with height.
• Now, we have to divide it by 2.

Answer :

(d) 12 ft²

Given :

• Shorten Base = 5 ft
• Longer Base = 7 ft
• Height = 2 ft

To find :

• Area of Poster

Solution :

$\sf Area \: of \: Poster = \dfrac{a + b}{2} \times h$

$\sf = \dfrac{5 + 7}{2} \times 2$

$\sf = \dfrac{12}{2} \times 2$

$\sf = \dfrac{24}{2}$

$\sf = 12$

Hence, Area of the Poster is 12 ft².
