The composite figure is made up of 2 rectangles.
Area of the top rectangle = 9 x 10 = 90 m²
Area of the bottom rectangle = 30 x 9 = 270 m²
Area of the figure = 90 + 270 = 360m²
Answer: Area = 360m²
We know that formular for volume of pyramid=area of base ×height
the area of the base is 1/2×base×height
=1/2×15×14
=105cm²
the given volume is 270cm³
∴height=volume÷base area
=270cm³÷105cm²
