Answer:
Area = 16 in²
Step-by-step explanation:
Represent the length with L and the width with W
We have the following given parameters:
L = 4W
Perimeter = 20
Required
Determine the area.
The perimeter is calculated as thus:
Perimeter = 2(L + W)
Substitute 4W for L and 20 for Perimeter.
20 = 2(4W + W)
20 = 2 * 5W
20 = 10W
Solve for W
W = 20/10
W = 2
Recall that:
L = 4W
L = 4 * 2
L = 8
The area is then calculated as thus:
Area = L * W
Area = 8 * 2
Area = 16
Hence, the area is 16in²

Answer:
Let Q be (x,y). Then AQ = 4QB; or (x - 2) = 4(4 - x) and (y + 1) = 4(2 - y);
x - 2 = 16 - 4x; 5x = 18 [ x = 3.6. y + 1 = 8 - 4y; 5y = 7, y = 1.4, So, Q(3.6, 1.4)
Answer:
270
Step-by-step explanation:
because 25% blue 30% pink
so 25+30=55
100-55=45
600×45%=270 shirts
