The length and width of the terrace are 15 feet and 6 feet respectively.
The area of the terrace is 90 ft²
The scale of the plan is 2 inches : 6 feet.
Therefore, 2inches represents 6 feet.
According to the drawing;
- length = 5 inches
- width = 2 inches
Therefore,
- length of the terrace = 5 × 6 / 2 = 30 / 2 = 15 feet
- width of the terrace = 2 × 6 / 2 = 12 / 2 = 6 feet
The area can be found as follows:
<h3>Area of a rectangle:</h3>
where
l = length
w = width
Therefore,
area = 15 × 6 = 90 feet²

Step-by-step explanation:
<span>Multiply one of the equations so that both equations share a common complementary coefficient.
In order to solve using the elimination method, you need to have a matching coefficient that will cancel out a variable when you add the equations together. For the 2 equations given, you have a huge number of choices. I'll just mention a few of them.
You can multiply the 1st equation by -2/5 to allow cancelling the a term.
You can multiply the 1st equation by 5/3 to allow cancelling the b term.
You can multiply the 2nd equation by -2.5 to allow cancelling the a term.
You can multiply the 2nd equation by 3/5 to allow cancelling the b term.
You can even multiply both equations.
For instance, multiply the 1st equation by 5 and the second by 3. And in fact, let's do that.
5a + 3b = –9
2a – 5b = –16
5*(5a + 3b = -9) = 25a + 15b = -45
3*(2a - 5b = -16) = 6a - 15b = -48
Then add the equations
25a + 15b = -45
6a - 15b = -48
=
31a = -93
a = -3
And then plug in the discovered value of a into one of the original equations and solve for b.</span>
