Answer:
(1) Area of second triangle= 50 cm^2.
(2) Area of ΔABC=98 cm^2.
and Area of ΔDFG=175 cm^2.
Step-by-step explanation:
<em>" For two similar triangles the ratio of sides is equal to the ratio of square of their areas".</em>
i.e. if a,b are the corresponding sides of two similar triangles and let A and B denote the area of two triangles then we have the relation as:

(1)
for the first question:
we have a=2, b=5.
A=8 cm^2.
Hence,

B=50 cm^2.
Hence, the area of second triangle is 50 cm^2.
(2)
In second option we have:
a=6 and b=5.
A-B=77 cm^2.
A=77+B

Hence area of second triangle i.e. ΔDFG is 175 cm^2.
and area of first triangle i.e. ΔABC=175-77=98 cm^2.
2.74 - (-19.4) = 22.14, so the freezer is 22.14°c colder. I hope that helps!
1/4":1' = 1/4" : 1'= 1:48
So the dimensions of the model are
L=80'/48=960"/48=20"
W=32'/48=384/48=8"

Divide the number of guest that came by the number of guests invited: 104/125=.832 or 83%. 83% of the invited guests were there :)
