True because i just did it and got it right
Answer:
Width of verandah = 1 m
Area of path = 234m²
Explanation:
Dimension of room :
6m by 4m
(6m * 4m) = 24m²
(6 + 2x)(4 + 2x) - 24 = 24
24 + 12x + 8x + 4x² - 24 = 24
4x² + 20x = 24
4x² + 20x - 24 = 0
x² + 5x - 6 = 0
x² + 6x - x - 6 = 0
x(x + 6) -1(x + 6) = 0
(x + 6) = 0 or (x - 1) = 0
x = - 6 or x = 1
x can't be negative, hence x = 1
B.)
Dimension of garden :
18 m by 15 m
Area of garden = 18 m * 15 m = 270 m²
Width of path which surrounds garden = 3m
Hence, dimension of path :
Area of garden and path
(18 +3 + 3)m by (15+3 + 3)m
24m by 21m
Area of path and garden = area of rectangle
Area of rectangle = Length * width
Area of rectangle = 24m * 21m
Aewa of path and garden = 504m²
.
Area of path :
Area of path and garden - Area of garden
504m² - 270m²
= 234m²
Katrina learned about curling by watching and focusing on the techniques used by the olympic players. By watching so much, she learned the movements and basic rules of the game. This is an example of visual learning which is also cognitive learning :-)
