This expression is factored completely. However, if we foil, we can make it to it's original expression.
When you foil, you get:

Answer: x = 29</h3>
======================================================
Work Shown:
x+61 = 90
x+61-61 = 90-61
x = 29
------------
Explanation:
- The first step is valid because the two angles x and 61 are complementary angles. They form a right angle or 90 degree angle.
- In the second step, I subtracted 61 from both sides to undo the "+61".
Answer: The area of the enclosure is 1,029 square meters
Step-by-step explanation: The first thing is to use the unit of measurement required by the question, and to do this we need to convert what we have to what is required.
If the scale of the diagram is given as every 4cm represents 7m, that means, every unit of the actual measurement would be given as
(X/4) x 7
For the length of the enclosure, we can determine that as follows;
Length = (28/4) x 7
Length = 7 x 7
Length = 49m
And for the width,
Width = (12/4) x 7
Width = 3 x 7
Width = 21m
Therefore, the area is calculated as,
Area = L x W
Area = 49 x 21
Area = 1029 m²
L = 4 + w
perimeter = 38
38 = w + 4 + w
2w = 34
w = 17
L = 4 + 17
L = 21
