Question

area and explanation thanks

Answer 1

The area of the rectangle is given by length × width so
40×25=1000
Now the area of the triangle is (1/2)base × height which is
$\frac{1}{2} \times 40 \times 25 = \frac{1}{2} \times 1000 = 500$
Now if we add the areas that gives us 1500 sq units. :)

Answer 2

Break this shape into two shapes, a rectangle and a triangle.

The are of the triangle is:

1/2 (40 x 25) = 500 units squared


Next, the area of the rectangle is:

25 x 40 = 1000 units squared

To find the total area, add the two. This, the total area is 1,500 units squared
