Let the length and breadth of each identical small rectangle be l and b. From Fig. 6.47, the top row has 4 rectangles placed lengthwise and the bottom row has 5 rectangles placed lengthwise along the same total width: 4l = 5b (or 4 of one dimension equals 5 of the other). Thus, l = 1.25b. The totalRead more
Let the length and breadth of each identical small rectangle be l and b.
From Fig. 6.47, the top row has 4 rectangles placed lengthwise and the bottom row has 5 rectangles placed lengthwise along the same total width:
4l = 5b (or 4 of one dimension equals 5 of the other).
Thus, l = 1.25b.
The total area of nine identical rectangles is 72 cm²:
9 x (l x b) = 72, which gives l x b = 8 cm².
Substitute l = 1.25b:
1.25b² = 8, so b² = 6.4, giving b = √6.4 ≈ 2.53 cm.
Then l = 8 / 2.53 ≈ 3.16 cm.
Perimeter of each small rectangle = 2(l + b) = 2(3.16 + 2.53) = 2(5.69) ≈ 11.38 cm.

Let the length and breadth of each identical small rectangle be l and b.
From Fig. 6.47, the top row has 4 rectangles placed lengthwise and the bottom row has 5 rectangles placed lengthwise along the same total width:
4l = 5b (or 4 of one dimension equals 5 of the other).
Thus, l = 1.25b.
The total area of nine identical rectangles is 72 cm²:
9 x (l x b) = 72, which gives l x b = 8 cm².
Substitute l = 1.25b:
1.25b² = 8, so b² = 6.4, giving b = √6.4 ≈ 2.53 cm.
Then l = 8 / 2.53 ≈ 3.16 cm.
Perimeter of each small rectangle = 2(l + b) = 2(3.16 + 2.53) = 2(5.69) ≈ 11.38 cm.
