Question

find the area of the trapezoid. if the answer is not an integer, leave it in simplest radical form, The figure is not to scale. (image included)

Answer 1

Answer:

420 ft^2

Step-by-step explanation:

$h = \sqrt{25 ^{2} - 7 }$

$= \sqrt{570}$

$= 24$

$a = \frac{1}{2} (b1 + b2)h$

$= \frac{1}{2} (14 + 21)(24)$

$answer = 420ft ^{2}$

Answer 2

Answer:

245 ft sq

Step-by-step explanation:

Find the are of the triangle and the square seperatly.

Area of a square is A = s * s

A = 14  * 14 = 196 ft sq

Focusing on the triangle, the dotted line is the same length as the bottom of the square. 14 ft

Area of a triangle is A = 1/2 * b * h

A = 1/2 * 14 * 7

A = 7 * 7

A = 49 ft sq

So, 196 + 49 = 245
