Me asap because if i don’t finish it i’ll get in trouble

SA= wh+lw+lp+ls

SA= 3(2)+7(3)+7(2.5)+7(2.5)

SA=6+21+17.5+17.5

SA=27+35

SA=62

To find the surface area of this solid figure we add the area of all the faces

formula for area of triangle = 1/2 * base * height

So Area of two triangles = 2( 1/2 * 3 *2) = 6 in^2

And area of two lateral rectangles = 2( length * width) = 2( 2.5 *7 ) = 2(17.5)= 35 in^2

And area of base rectangle = (3*7) in^2 = 21 in^2

Now adding all the areas we get

(6+35+21) in^2 = 62 in^2

So surface area = 62 in^2
