Question

I need math help please

Answer 1

To find the area of the shaded region, we need to subtract the area of the rectangle from the area of the larger rectangle.

First,you find the area of the larger rectangle. The length of the larger rectangle is 11 m and the width is 7 m. To find the area, we multiply the length by the width: 11 m * 7 m = 77 m².

Next, you find the area of the rectangle inside the shaded region. The length of this rectangle is 4 m and the width is 2 m. To find the area, we multiply the length by the width: 4 m * 2 m = 8 m².

Now, you can calculate the area of the shaded region by subtracting the area of the rectangle from the area of the larger rectangle: 77 m² - 8 m² = 69 m².Therefore, the area of the shaded region is 69 m².

Answer 2

30 m²

Explanation:

Let the given figure is complete rectangle.

We can find the area of shaded region by subtracting area of non shaded rectangle from complete rectangle.

Since

Area of rectangle is product of length and width.

So, the area of the complete rectangle = 11m × 4m = 44m²

and

Area of non shaded rectangle= 7m × 2m = 14 m²

Now,

Area of shaded rectangle = Area of complete rectangle - Area of non shaded rectangle

= 44m² - 14m²

= 30m²

Therefore, the area of the shaded region is 30 m²
