1 khu đất hình chữ nhật có chiều rộng kém chiều dài 42m nếu giảm mỗi chiều 5m thì lúc đó chiều dài gấp 7 lần chiều rộng tìm diện tích
A 132 m2
B 88 m2
C 343 m2
D 648 m2
Đáp án là:
D. 648 m2
bài giải
Chiều rộng hình chữ nhật lúc sau là :
42 : (7 - 1) x 1 = 7 ( m )
Chiều rộng hình chữ nhật ban đầu là :
7 + 5 = 12 ( m )
Chiều dài hình chữ nhật làn :
12 + 42 = 54 ( m )
Diện tích hình chữ nhật là :
54 x 12 = 648 ( m2 )
