Answer 1

`\huge\boxed{\sf area \ of \ \triangle= 45 \ cm^2}`

Step-by-step explanation:

`\huge\boxed{\sf area \ of \ \triangle = (1)/(2)* base * height }`

`\huge\boxed{\sf area \ of \ \triangle= (1)/(2) * 12 * 7.5 }`

`\huge\boxed{\sf area \ of \ \triangle= (1)/(2)*90 }`

`\huge\boxed{\sf area \ of \ \triangle= 45 }`
