Answer:
area = 36 m^2
perimeter = 34m
Step-by-step explanation:
Area of a trapezoid is calculated by the following formula:
(a+b)/2 * h (a: base, b: base, h:height)
(6+12)/2 * 4 = 36 the area is 36 m^2
The perimeter is calculated by adding all side lengths or multiplying the sum of non-parallel sides by 2
Only the measure of AB=AC is missing to find it we can use the method in attached photo
and the perimeter is:
(12+5)*2 = 34
