Hello Brainly, Please send the details for the area of each shape. Sincerely, Leanoriaia

This type of problems are solved by partitioning the figure into rectangles, whose areas we can find easily.
Picture 1)
From the point denoted by E, draw two altitudes towards the sides AG and AC.
Since ED is 3, then BC is 3. Thus, AB=4-3=1.
Since EF is 1, then HG is 1, so AH=3-1=2.
The area of the figure is equal to the area of rectangle ACDH + the area of the square HEFG.
That is, the area of the figure is 4*2+1*1=8+1=9 (square in).
Picture 2)
As in the first part, draw the altitudes EB and EH from point E.
GF is 5, so AB is 5. This means that BC=7-5=2 (in).
FE is 3, so GH is 3, that is HA=6-3=3.
Thus, Area(figure)=Area(ABFG)+Area(BCDE)=5*6+2*3=30+6=36 (square in.)
Answer: 9 (square in); 36 (square in.)

Answer:
Small Scale replica of John Hancock tower is approximately 2.33 m.
Step-by-step explanation:
Given:
Height of Willis tower = 1450 ft
Height of John Hancock Center = 1127 ft
Small Scale replica of Willis tower = 3 m
We need to find Small Scale replica of John Hancock tower.
First we will find the per meter scale of Willis tower and then using the same we will use to find the Small Scale replica height of John Hancock tower.
For 3 meter scaling = 1450 ft
So for 1 meter scaling = Number of foots in 1 meter Scaling
By Using Unitary method we get;
Number of foots in 1 meter Scaling =
Now we had 1 meter scaling as 483.333 ft and we need to find meter scaling for 1127.
So again Using Unitary method we get;
Small Scale replica of John Hancock =
Rounding to nearest hundred we get;
Small Scale replica of John Hancock tower is approximately 2.33 m.
