Answer 2

Answer:

135 cm²

Step-by-step explanation:

Step 1 : Let us first understand the question

Here, quadrilateral ABCD has 2 triangles inside it with their base and height given,

Therefore, Area of quadrilateral ABCD = Area of triangle ABC + Area of triangle ADC

Step 2 : Find out the area of triangle ABC

Area of triangle ABC = 1/2×20×5

Area of triangle ABC = 10×5

Area of triangle ABC = 50 cm²

Step 3 : Find out the area of triangle ADC

Area of triangle ADC = 1/2×20×8.5

Area of triangle ADC = 10×8.5

Area of triangle ADC = 85 cm²

Step 4 : Sum the areas of both triangles

Area of quadrilateral ABCD = Area of triangle ABC + Area of triangle ADC

Area of quadrilateral ABCD = 50 + 85

Area of quadrilateral ABCD = 135 cm²
