Question

help me please. thank you!

Answer 1

The shape above is a trapezium, so we are going to use the formula for the area of a trapezium which is,

$area = (\frac{a + b}{2} )h$

Plugging in our values,

$area = ( \frac{2 + 8}{2} ) \times 3 = ( \frac{10}{2} ) \times 3 = 5 \times 3 = 15 {cm}^{2}$

So the area will be

$15 {cm}^{2}$
