The length of a rectangle is twice its breadth. If its length is decreased by 5 cm and breadth is increased by 5 cm, the area of the rectangle is increased by 70 sq. cm. Find the length of the rectangle. | [
"16cm",
"20cm",
"18cm",
"12cm"
] | C | Explanation:
Let breadth = x. Then, length = 2x. Then,
(2x - 5) (x + 5) - 2x * x = 70 => 5x - 25 = 70 => x = 18.
Length of the rectangle = 18 cm.
