Answer 2

Area of pyramid = 14 square meter

Step-by-step explanation:

Area of one right angled triangle
`=(1)/(2)` (base) (height)

Put base
`=2` m, height
`=2.5` m

Area of one right angled triangle
`=(1)/(2)` (2)(2.5) = 2.5 square meter

Area of 4 right angled triangles
`=4(2.5)=10` square meter

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

So,

Area of pyramid = 10 + 4 = 14 square meter
