A triangular prism is composed of 2 triangles and 3 rectangles.
1 triangle has 2 right triangle, for a total of 4 right triangles.
Area of a right triangle = ab/2 = (3.5m * 2m)/2 = 7/2 = 3.5m²
3.5m² x 4 right triangles = 14 m² total area of the triangle bases.
Rectangle: length = 11 m ; width = 4m
Area of a rectangle = L * W = 11m * 4m = 44m²
44m² x 3 rectangles = 132 m² total area of the rectangle faces
<span>Surface area = 132 m² + 14 m² = 146 m²

Step-by-step explanation:
Let the length be L.
Let the breath be B.
So, we are given that
length of a rectangle is 7 inches greater than three times its width .
So, according to the Question,
L = 7+ 3B.
So, we know that:-
Area = Length× Breadth.
So, it will be
B × (7 + 3B) = Area.
So,
3B² + 7 is an expression to represent its area.
