In the figure, ABCD is a rectangle; E is the midpoint of AD; F is the midpoint of CD. What is the ratio between the area of the rectangle ABCD and the area of the triangle AEF?
How many rectangle(s) with “*” is / are there in the figure below?
các bạn giúp mình giai bài này và dịch hộ mình bài này nhé
in the figure ,MNPQ is square.Each its side is 15cm long. MNHQ is a rectangle and its width is 12cm shorter than its length. The perimeter of the rectangle GNPH is .............cm
Trong hình , MNPQ là hình vuông, mỗi bên của nó dài 15 cm. MNHQ là hình chữ nhật và chiều rộng của nó là 12cm ngắn hơn chiều dài của nó. Chu vi hình chữ nhật GNPH là ....... cm.
Mình chỉ bít dịch thôi . Sorry bạn nh1. Có gì thì k cho mình nha
In the following figure, ABED and BCFE are square. If the perimeter of the rectangle ACFD is 54cm then its area is
Can you translate it into Vietnamese for me? I'm not good at English:))
Cho hình sau, ABED và BCFE là hình vuông. Nếu chu vi của hình chữ nhật ACFD là 54cm thì diện tích của nó là bao nhiêu?
tong chieu dai va chieu rong cua 2 hinh vuong la
54:2=27
chieu rong la
27:(2+1)x1=9 cm
chieu dai la
9x2=18 cm
dien tich cua ACFD la
9x18=162 cm2
The rectangle ABCD is divided into 4 regions whose perimeters are indicated in the figure below,where X,Y,Z Are Distinct positive integers and X>Y .It is known that Z=\(\frac{X+Y}{3}\)and W<6.Find X

bạn nào trả lời lung tung sẽ ko đc tick đâu nha!
bn vt thế làm sao tụi tui hiểu dc
Let the rectangle ABCD, AB=2/3BC and the area is 24cm2. What is the perimeter of the rectangle ABCD
We have \(S_{ABCD}=AB.BC=\frac{2}{3}BC.BC=\frac{2}{3}BC^2\)
So \(\frac{2}{3}BC^2=24\Rightarrow BC^2=36\Rightarrow BC=6\Rightarrow AB=4\) (cm)
\(\Rightarrow\) The perimeter of ABCD is \(2.\left(4+6\right)=20\left(cm\right)\)
1/- Compare : A = (1+3+5+...+139)/70 and B = (2+4+6+...+138)/69
Answer : A......... B
2/- In the follwing figure , ABED and BCFE are square . If the perimeter of the rectangle ACFD is 54cm . Then its area is :
3/- Calculate : 4/16 + 6/15 + 8/14 + 3/7 + 3/5 + 3/4 = ?
( Write your answer in the simplest form . )
1/ A=B
2/ The rectangle ACFD's area is 162cm^2
3/ 3
