area of a triangle is equal of the area of a square of side 60 m. Find the side of the triangle whose corresponding altitude is 90 m.

area triangle=areaside

1/2 bh=s^2
1/2 b*90=60^2

solve for b.

I am not certain which of the three sides you wanted on the triangle.

80m

To find the side of the triangle whose corresponding altitude is 90 m, we need to use the formula for the area of a triangle:

Area of a triangle = (base * height) / 2

We are given that the area of the triangle is equal to the area of a square with a side length of 60 m. Let's calculate the area of the square first:

Area of square = side * side = 60 m * 60 m = 3600 m^2

Since the area of the triangle is equal to the area of the square, we have:

Area of triangle = 3600 m^2

And the height (altitude) of the triangle is given as 90 m. Plugging these values into the formula, we can solve for the base (side) of the triangle:

3600 m^2 = (base * 90 m) / 2

To solve for the base, we can rearrange the formula:

base = (2 * 3600 m^2) / 90 m

base = 80 m

Therefore, the side of the triangle whose corresponding altitude is 90 m is 80 m.
