Q. If a rectangle has a length that is twice its width and the perimeter is 48 cm, what is the area of the rectangle?

A. 96 cm²
B. 144 cm²
C. 192 cm²
D. 256 cm²

Solution

Let width = w, then length = 2w. Perimeter = 2(length + width) = 48. Thus, 2(2w + w) = 48, leading to 6w = 48, so w = 8 cm. Area = length * width = 2w * w = 2*8*8 = 128 cm².

Correct Answer: B — 144 cm²

Q. If a seller incurs a loss of 10% on selling a bicycle for $450, what was the cost price?

A. $500
B. $450
C. $400
D. $350
