Step-by-step explanation:
Given that,
AD = 20cm
DC = 15cm
BC = 7cm
AB = 24cm
Since the shape consist of two right angle triangle,
Then, we will find the area of each triangle and add them together to find the area of the quadrilateral ABCD
Area of a triangle can be calculated using
A = ½b×h
Then,
For triangle 1, its area is
A_1 = ½ × DC × AD
A_1 = ½ × 15 × 20
A_1 = 150 cm²
Fro triangle 2
A_2 = ½ × BC × AB
A_2 = ½ × 7 × 24
A_2 = 84 cm²
Then, the total area is
A = A_1 + A_2
A = 150 + 84
A = 234 cm²
Area of the quadrilateral ABCD is 234cm²
