Answer:
33 by 45 meters
Step-by-step explanation:
The perimeter is twice the sum of adjacent side lengths, so the sum of the dimensions is 78 meters. If x is one of the dimensions, then 78-x is the other, and the area is their product:
x(78 -x) = 1485
Subtracting the left side, we get ...
x^2 -78x +1485 = 0
This can be graphed as ...
y = x^2 -78x +1485
and the zeros will reveal the dimensions.
The attached graph shows them to be ...
33 by 45 meters
For this answer, divide 30 by 6.
30 / 6 = 5

Answer:
Height of the taller building is 63.5ft
Step-by-step explanation:
Kindly find attached rough sketch of the problem for your reference.
Let the small building be A and the taller building be B
From the sketch the two buildings form a right angle triangle
We can solve for x which is the height of the taller building relative to the small building using
SOH CAH TOA
Applying TOA we have
Tan θ= opposite/adjacent
Tan 42°= x/35
x= Tan 42*35
x= 0.9*35
x= 31.5ft
Hence the height of the taller building is = x+height of small building = 31.5+32= 63.5ft
