What is the missing width of tie rectangle With width of 6cm Height of 4cm and Surface area of 188cm
Apologies for the error. Let's correct the calculation:
Given width = 6 cm, height = 4 cm, and surface area = 188 cm²:
Surface area = 2(length x width) + 2(width x height)
188 = 2(length x 6) + 2(6 x 4)
188 = 12 length + 48
12 length = 140
length = 140 / 12
length = 11.67 cm
The missing width of the rectangle should be:
Surface area = 2(11.67 x 7) + 2(7 x 4)
188 = 2(81.69) + 2(28)
188 = 163.38 + 56
188 = 219.38
So, the missing width of the rectangle should be approximately 7 cm. Thank you for pointing out the mistake.
The surface area of a rectangle is given by the formula:
Surface area = 2(length x width) + 2(width x height)
Given width = 6cm, height = 4cm, and surface area = 188cm, we can plug in these values to find the missing length:
188 = 2(length x 6) + 2(6 x 4)
188 = 12length + 48
140 = 12length
length = 140/12
length ≈ 11.67 cm
Therefore, the missing width of the rectangle is 11.67 cm.
