In the diagram u can see
 1 square and 4 triangles
let's find the area of the square = side²
                                                  =
3²= 9 sq.cm
now we find area of triangle = 1/2 base × height
                                             = (3 × 2.5)/2
                                             = 7.5 /2
                                             = 3.75 sq.cm
area of four triangles = 4 ×3.75= 15 sq. cm
area of the diagram = area of square + area of the four triangles
                                = 9 sq.cm +  15 sq.cm
                                = 24 sq.cm
