The base of the triangle is 5 inches. The length of the rectangle is 15 inches. The height of the triangle is 10 inches. Find the surface area

275 square inches

Step-by-step explanation:

Here we have to give us various measurements, but we do not know to which figure it corresponds since you do not attach it, but I have found an image where they asked the same questions and it makes sense that it is the question, the attached one.

We have that the rectangle is 15 inches long and the width corresponds to the same as the base of the triangle, that is, 5 inches, therefore, the area of the rectangle would be:

A = l * w

A = 15 * 5

A = 75

75 in ^ 2 but how are 3 rectangles would be:

75 * 3 = 225

225 in ^ 2 would be the area of the 3 rectangles, it would be necessary to add the area of the two triangles that would be:

A = b * h / 2

replacing:

A = 5 * 10/2

A = 25

25 in ^ 2 for the triangle, but being 2, they would be 50 ^ 2, now in total they would be:

225 + 50 = 275

In other words, the surface area of the figures is 275 square inches
