Ta coi chiều dài và rộng ban đầu là 100% và diện tích ban đầu là 1

Chiều dài mới là: 100% + 10% = 110%

Chiều rộng mới là: 100% - 20% = 80%

Đổi: 110% = 1,1                        80% = 0,8

Diện tích hình chữ nhật mới là: 1,1 x 0,8 = 0,88 = 88% (1)

Diện tích hình chữ nhât mới là: 50 : 100 x 88 = 44 ( m²)

Đáp số: 44m²

Diện tích của một hình chữ nhật là 50 m2 . Nếu nó chiều dài là tăng 10 % và chiều rộng của nó là giảm 20 % thì diện tích của hình chữ nhật mới là ?
