I just learned this, I believe that the answer is <span>a1=21;an=7⋅an−1</span>
First find the area of the rectangle by multiplying the length and width of the rectangle, so 12 x25=300. Then find the area of the triangle, which is length x height/ 2. So 8 x 25=200/2=100. Then add the two answers together to get 400.
Please write out the entire question so we can do our best to assist you with the most logical response.
Hope this helps!
