Answer 1

Answer:

The length and breadth of a rectangle are 10 cm and 8 cm respectively. If its length is doubled, then its new area is. 160 cm.

Answer 2

Answer:

160cm²

Step-by-step explanation:

Length = L = 10cm

Breadth = B = 8cm

Area of the rectangle = L × B = 10 × 8 = 80cm

If the length of the rectangle is doubled,

New Length = l = 10 × 2 = 20cm

Breadth = 8cm

New area of the rectangle = l × B = 20 × 8 = 160cm²
