What about it? What is the question?
63 cmPerimeter = 2 x (Length + Width) = 2 x (9cm + 7cm) = 2 x 16cm = 32cm
35 cm
Area= length x width. Therefore, Area= 7cm x 4cm=28cm squared.
This is a rectangle, not a square, but the problem is solved in the same manner. Multiply length x width. You did not provide units for the 2 and 7, so I'll give you some answers with various units. If the units for length and width are centimeters, A = 2cm x 7cm = 14cm2. If the units for length and width are meters, A = 2m x 7m = 14m2. If the units for length and width are inches, A = 2in x 7in = 14in2. If the units for length and width are feet, A = 2ft x 7ft = 14ft2.

It is: 4*7 = 28 square cm
The width is 10.5 cm.
length + width = 20/2 = 10 length = 7cm, width = 3cm
First find the dimensions of the rectangle. Let the length be x+4 and the width be x: 2(x+4+x) = 20 2x+8+2x = 20 4x = 20-8 4x = 12 => x = 3 Therefore: length = 7cm and the width = 3cm Area = length*width => 21cm2
The area of a rectangle is calculated by multiplying the length by the width. 7cm x 3.5cm = 24.5 cm2 - cm2 = centimeters squared
It depends on whether you want the width as a fraction of the length or perimeter or something else - like the diagonal.
Multiply the two numbers together - and you get 35 cm2
Assuming that this is a rectangle, you know that the length (longer side) would be 7cm, and the width (shorter side) would be 6cm. The formula for perimeter is, 2(length) + 2(width) = Perimeter Now we can plug in our numbers, 2(7cm) + 2(6cm) = 14cm + 12cm = 26cm The perimeter would be 26cm, assuming that this is a rectangle ^^
Given: p = 26cm and 2x width - 5cm = length p = 2(a+b) = 26cm; a+b = 13cm 2x6-5=7 The sides of the rectangle are: width 6cm and length 7cm
63 cmPerimeter = 2 x (Length + Width) = 2 x (9cm + 7cm) = 2 x 16cm = 32cm
To work out the area of a rectangle you simply multiply the width by the length:Here the width and length are 7 and 8 so by multiplying them together you get:56Remember, that if units are involved such as centimetres, you must write a squared sign after the digits. For example if it were 7cm and 8cm, you would write the answer as 56cm2
