Question

7. The ratio of the length and the breadth of a
rectangular plot is 8: 5. If the area of the plot is
640 sq cm, find its dimensions.​

Answer 1

Answer:

area of rectangular plot = l * b = 640 cm²

= 8x * 5x = 640

= 40x² = 640

= x² = 640 /40 = 16

= x = ✓ 16 = 4

length = 8 * 4 = 32

breadth = 5 * 4 = 20
