1.

side of a rectangle are 20 cm and 15 CM if each side of the rectangle is increased by 20% find the percentage increase in the area

Answer»

Bonjour !!!❤❤

LENGTH = 20 CM

Breadth = 15 cm

Area = 20 × 15 = 300 cm²

Increase in length = 20/100 × 20 = 4cm

New length = 24 cm

Increase in breadth = 20/100 × 15 = 3cm

New breadth = 18 cm

New area = 24 × 18 = 432 cm²

Increase in area = 432 - 300 = 132 cm

% Increase = 132/300 × 100

= 44%


Hope it helps....✌✌
