Find the area of the entire rectangle?

48

Step-by-step explanation:

the triangle is half the area of the rectangle. this is because the width and length of the triangle is the same as the length and width of the rectangle. since the formula for the area of a triangle is (L*W)/2, the rectangle is just twice the area, since it's formula is L*W

so 24 * 2 = 48
