91 The perimeter of a square is 20 cm. A rectangle has the same width as the square. The length of the rectangle is double its width. The area, (in sq cm) of the rectangle is

Perimeter of square = 20 cm
∴ 4 × Side = 20
Side = 20/4 = 5 cm
Now, Side of square = Width of rectangle
= 5 cm
and Length of rectangle = 2 × Width
= 2 × 5 = 10 cm
Now, Area of rectangle = Length × Breadth
= 10 × 5 = 50 cm²

92 The internal length, breadth and height of a rectangular Box A are 20 cm, 18 cm, and 15 cm respectively and that of Box B are 18 cm. 12 cm and 5 cm respectively. The volume of Box A is how many times that of Box B?

Given, length, breadth and height of Box A are 20 cm, 18 cm and 15 cm respectively.
∴ Volume of Box A = Length × Breadth × Height
= (20 × 18 × 15) cm³
Similarly, Volume of Box B = (18 × 12 × 5) cm³
Now, required ratio

93 Which of the following is not correct?

From the given options,
Option (A), Area of square of side 10 cm = Side² = (10)² = 100 cm²
Now, are of rectangle of length 10 cm and breadth of 0.1 m or 10 cm.
= 10 × 10 = 100 cm² (true)
Option (B), 1 m 5 cm = 1.50m ≠ 1.5 m (false)
Option (C), 0.40 is same as 0.4, as zero after decimal value is irrelevent. (true)
Option (D), On dividing 3 by 4, we get 0.75
∴ ₹3/4 = ₹0.75 (true)
