Dịch được như sau:
Một nửa chu vi của sân trường hình chữ nhật là 0,24 km. Chiều rộng là chiều dài. Tìm diện tích sân trong mét vuông?
Giải:
Vì chiều dài là chiều rộng nên ta có:
đổi 0,24km= 240m
Chiều rộng và chiều dài là:
240 : 2=120 (m)
Diện tích của sân trường là:
120 . 120=14 400 (\(m^2\))

A rectangular area of 6 m square.
A / Calculate the length, width.
B / Calculate rectangular perimeter.
Rectangular area of 6 m square.
Dịch: hình chữ nhật diện tích 6 m2.
a, Calculate the length, width.
Dịch: tính chiều dài, chiều rộng.
b, Calculate rectangular perimeter.
Dịch: tính chu vi hình chữ nhật.
Giải:
b, Chu vi hình chữ nhật là: 6 : 2 = 3 (m)
Chiều dài lớn hơn chiều rộng mà chu vi là 3 m thì:
=> Chiều dài: 2 m
=> Chiều rộng: 1 m
ĐS: a, Chiều dài: 2 m
Chiều rộng: 1 m
b, Chu vi: 3 m
Dịch sang tiếng anh nếu cần:
Solution:
b, rectangular perimeter is: 6: 2 = 3 (m)
The length is greater than the width at which the perimeter is 3 m:
Length: 2 m
= Width: 1 m
Track: a, Length: 2 m
Width: 1 m
b, circumference: 3 m

Please help me to solve this problem:
A rectangular schoolyard has a length of 65m and a width equal to 4/5 of its length. Calculate the perimeter and area of that schoolyard.
Please write to me!!!
the area of theschoolyard = 65x (4/5x65)= 65 x 52 = 3380 m2
the perimeter of the schoolyard= 2 x(65+52) =234m
the width is : 65 : 5 * 4 = 52 ( m )
the perimeter is : ( 65 + 52 ) * 2 = 234 ( m )
the area is : 65 * 52 = 3380 ( m2 )
