To solve this, you first add the parts of the ratio (5+12), which totals 17 parts. Divide the total number of shirts (340) by the total parts (17) to get shirts per part (20). Finally, you multiply the number of parts for blue shirts (5) by the number of shirts per part (20), resulting in 100 blue shirts.
In order to determine how many shirts are blue, we must first understand the concept of ratios. In this case, the total ratio is given as 5:12, representing the ratio of blue shirts to green shirts respectively. This ratio means for every 5 blue shirts, there are 12 green shirts.
The total number of shirts given is 340. To find out the number of blue shirts, we first add the parts of the ratio together. 5 (for blue) + 12 (for green) equals a total of 17 parts. To find the value of a single part, we divide the total number of shirts by this number: 340 shirts ÷ 17 parts = 20 shirts per part.
Since we know there are 5 parts for the blue shirts, we simply multiply this by the number of shirts per part: 5 parts (blue) * 20 shirts per part = 100 blue shirts.

Let the width=x mtr
So the length will be x+8 mtr
so the are of the rectangle will be=x(x+8)=240
x²+8x=240
x²+8x-240=0
x²+20x-12x-240=0
x(x+20)-12(x+20)=0
(x+20)(x-12)=0
x-12=0 i.e x=12 mtr
so the length=12+8=20 mtr

Step-by-step explanation:
yards of sod. Give the dimensions of two
different rectangular regions that she can
cover with the sod. What is the perimeter
of each region?
Answer:
The dimensions of the two different rectangular regions are;
1st Arrangement:
W = 4 yards and L = 5 yards or W = 5 yards and L = 4 yards
2nd Arrangement:
W = 2 yards and L = 10 yards or W = 10 yards and L = 2 yards
The perimeter of the two different rectangular regions are;
1st Arrangement:
P₁ = 18 yards
2nd Arrangement:
P₂ = 24 yards
Step-by-step explanation:
Bella is putting down patches of sod to start a new lawn.
She has 20 square yards of sod.
We are asked to provide the dimensions of two different rectangular regions that she can cover with the sod.
Recall that a rectangle has an area given by
Area = W*L
Where W is the width of the rectangle and and L is the length of the rectangle.
Since Bella has 20 square yards of sod,
20 = W*L
There are more than two such possible rectangular arrangements.
Out of them, two different possible arrangements are;
1st Arrangement:
20 = (4)*(5) = (5)*(4)
Width is 4 yards and length is 5 yards or width is 5 yards and length is 4 yards
2nd Arrangement:
20 = (2)*(10) = (10)*(2)
Width is 2 yards and length is 10 yards or width is 10 yards and length is 2 yards
Therefore, the dimensions of two different rectangular regions are;
1st Arrangement:
W = 4 yards and L = 5 yards or W = 5 yards and L = 4 yards
2nd Arrangement:
W = 2 yards and L = 10 yards or W = 10 yards and L = 2 yards
What is the perimeter of each region?
The perimeter of a rectangular shape is given by
P = 2(W + L)
Where W is the width of the rectangle and and L is the length of the rectangle.
The perimeter of the 1st arrangement is
P₁ = 2(4 + 5)
P₁ = 2(9)
P₁ = 18 yards
The perimeter of the 2nd arrangement is
P₂ = 2(2 + 10)
P₂ = 2(12)
P₂ = 24 yards
So the perimeter of the 1st arrangement is 18 yards and the perimeter of the 2nd arrangement is 24 yards.
Note:
Another possible arrangement is,
20 = (1)*(20) = (20)*(1)
Width is 1 yard and length is 20 yards or width is 20 yards and length is 1 yard.
