Answer:
1. Area of rectangular rug is 
2. Area of triangular room is 
Step-by-step explanation:
This problem bothers on the mensuration of flat shapes, rectangle and triangle.
step one
let us start by solving for the area of the rectangular rug
given data
Area A = ?
Length l = 11 ft
Width w= 10 ft
we know that the area of a rectangle is expressed as
substituting our given data we have
step two
let us solve for the area of the triangular room
given data
Area A = ?
base b = 30 ft
height h= 22 ft
we know that the area of a triangle is expressed as
substituting our given data we have
Multiply 2nd equqation by -1 and add to first
5x+4y=22
<u>-3x-4y=-10 +</u>
2x+0y=12
2x=12
divide by 2
x=6
sub back
3x+4y=10
3(6)+4y=10
18+4y=10
minus 18 both sides
4y=-8
divide by 4
y=-2
(x,y)
(6,-2) is solution
The Lowest Common Denominator of 3 and 4 is the denominator that will
simplify mathematical operations such as addition of the fractions.
- The mistake is the LCD of 3 and 4 is 12 rather than 24
Reasons:
The given fractions are;
The Lowest Common Denominator, is given by the Least Common Multiple of the denominators, which is 3 × 4 = 12
Therefore;
The LCD = 12
The equivalent fractions are therefore;
Therefore, the mistake is using a LCD of 24 rather than 12, given that 12 is lower than 24 and therefore is the LCD of 3 and 4.
By having an LCD of 12, we have;
The equivalent fractions with the LCD will be;
