Respuesta :

Answer:

Area of pyramid = 14 square meter

Explanation:

Area of one right angled triangle [tex]=\frac{1}{2}[/tex] (base) (height)

Put base [tex]=2[/tex] m, height [tex]=2.5[/tex] m

Area of one right angled triangle [tex]=\frac{1}{2}[/tex] (2)(2.5) = 2.5 square meter

Area of 4 right angled triangles [tex]=4(2.5)=10[/tex] square meter

Area of square = side × side = 2 × 2 = 4 square meter

So,

Area of pyramid = 10 + 4 = 14 square meter
