I need help on this mathematics question
Can anyone help?

42.5 units²

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = h (a + b)

where a and b are the parallel bases and h the perpendicular height

Here a = 5, b = 12 and h = 5, thus

A = 0.5 × 5 × (5 + 12) = 0.5 × 5 × 17 = 42.5 units²

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

its c or d   take a lucky guess my dude
