What is the area of this face?
400 in2
200 in2
150 in?
100 in2

200 in^2

area of 1st square

A=S×S

=10in×10in

=100in^2

area of 2nd square

A=s×s

=10in×10in

100in^2

total area=100in^2+100in^2=200in^2

200 in^2

Step-by-step explanation:

It can be determined by the given measurements that the top length of the shaded area is 10in, along with the lower right side length. To find area, multiply length by height.

The find the area of a compound surface, add the measured areas.

Multiplying the length (10) by the height (10) on the first visible square will lead to the area of 100in^2.

Do the same to the second visible surface to get 100in^2.

Add these together to get 200in^2.

I hope this helps :)

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°
