Hey there :)
1st Shape:
It is a trapezium
We know the area formula of a trapezium
Area = [tex] \frac{1}{2}(base1+base2)(height) [/tex]
We know the:
Base 1 = 4 units
Base 2 = 8 units
Height = 6 units
Apply the formula:
A = [tex] \frac{1}{2}(4+8)(6) [/tex] = 36 units²
2nd Shape:
It is a trapezium
We are given:
Base 1 = 8 units
Base 2 = 16 units
Height = 14 units
Apply the formula
Area = [tex] \frac{1}{2} (8+16)(14)[/tex] = 168 units²
