72 feet squared

Step-by-step explanation:

First of all, you need to work out how long each side is.

√576 = 24

Now we know that each side is 24 feet long.

The triangle area of the square has points that reach halfway through the aides of the square, so they are 12 feet long each.

If we multiply 12 by 12, we get 144, but that gives us the area of a SQUARE, so we must divide the sum by two, to make it the area of a TRIANGLE.

144 ÷ 2 = 72

The amount of area taken up by the cafe is 72 feet squared.

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
