Answer 2

length=10 cm

length=10 cmbreadth=8cm

length=10 cmbreadth=8cm(given)

length=10 cmbreadth=8cm(given)Doubled length: 10 × 2= 20cm

length=10 cmbreadth=8cm(given)Doubled length: 10 × 2= 20cmAREA OF RECTANGLE= L ×B

length=10 cmbreadth=8cm(given)Doubled length: 10 × 2= 20cmAREA OF RECTANGLE= L ×B= 20 × 8

length=10 cmbreadth=8cm(given)Doubled length: 10 × 2= 20cmAREA OF RECTANGLE= L ×B= 20 × 8= 160 cm²

length=10 cmbreadth=8cm(given)Doubled length: 10 × 2= 20cmAREA OF RECTANGLE= L ×B= 20 × 8= 160 cm² therefore, the new area of rectangle is 160 cm².
