Answer:
Option (c) is correct.
total area of figure = 390 cm²
Step-by-step explanation:
The given figure consist of two shapes a rectangle of length 20 cm and breadth of 15 cm and a triangle at top with base 15 cm and height 12 cm.
We have to find the area of this figure,
To find the area add the area of the two figure
Area of rectangle = length × breadth
Substitute, we get
Area of rectangle = 20 × 15
Area of rectangle = 300 cm².
Area of triangle = [tex]\frac{1}{2 } \cdot {base} \cdot height[/tex]
Substitute, we get
Area of triangle = [tex]\frac{1}{2 } \cdot 15 \cdot 12[/tex]
Area of triangle = 90 cm²
Thus, total area of figure = Are of rectangle + area of triangle
total area of figure = ( 300 + 90 ) cm²
total area of figure = 390 cm²
Hence, option (c) is correct.
