Q1: In a right-angle triangle the base is 50 m long and its height is 40 m .find its area

Area = (1/2) b h

1000m

Wrong.

Area is not measured in meters.
It would be 1000 square meters.

To find the area of a right-angled triangle, we can use the formula:

Area = (1/2) * base * height

In this case, the base is given as 50 m and the height is given as 40 m. So, we can substitute these values into the formula:

Area = (1/2) * 50 * 40

Now let's calculate the area:

Area = 0.5 * 50 * 40
= 0.5 * 2000
= 1000

Therefore, the area of the right-angled triangle is 1000 square meters.
