Answer 1

B

Explanation:

Answer 2

The correct option is A.

Explanation:

The area of a triangle is

`A=(1)/(2)* base* height`

From the given figure it is clear that the base of the triangle STR is 6 ft and the height of the triangle 10 ft. So, the area of triangle STR is

`A=(1)/(2)* 6* 10`

`A=3* 10`

`A=30`

The area of triangle STR is 30 square ft. Therefore the correct option is A.
