Area of triangle:
- 1/2 * base * height
- 1/2 * 16 * 7
- 56 m²
Area of upper rectangle:
- Length * Width
- 8 * 9
- 72 m²
Area of bottom rectangle:
- Length * Width
- 6 * 3
- 18 m²
Total area:
- 18 m² + 72 m² + 56 m²
- 146 m²
Answer:
Step-by-step explanation:
So the Dimensions are:
Height: 300cm
Length: 300cm
Width: 2cm
SA = 2(H*L)+2(H*W)+2(L*W)
= 180000 + 1200 + 1200
= 182400 OR 18.24
Let x be a number of skateboards and y be the number of bicycles in Eddie's repair shop.
Eddie asks the girls to order 54 new wheels for 21 skateboards and bicycles, then
x+y=21.
One scateboard has 4 wheels, then x scateboards have 4x wheels, one bicycle has 2 wheels, then y bicycles have 2y wheels. In total there should be ordered 54 wheels, so
4x+2y=54.
Solve the system of equations:
From the first equation Substitute it into the second equation:
Then
Answer: 6 scateboards and 15 bicycles.
