Calculate the area of the shape

Mathematics
1 answer:
Oduvanchick [21]3 years ago

<h2>Answer:   a. 164 u²</h2>

Step-by-step explanation:

Area of a trapezium  = ¹/₂ (a + b) h

But the height isn't given. So we have to solve for it.

h = √(10² - 6²)        <em> [using the Pythagorean theorem]</em>

<em>  </em> =  8

       

∴ Area of the shape =   ¹/₂  (13 + 28) 8

                                 =  164 u²
