What is the answer to this question​

First find the area of the square

(s x s)

10x10

=100

And then for the triangles

(1/2bh)

1/2 x 10 x 12

=60

since there are 4 triangles of the same area we will multiply 4 with the first triangle's area

60 x 4

=240

Total S.A= 240 + 100

=340 Square Inches

Option B

Hope it helps!
