The length of a rectangle is 4cm longer than the width if the perimeter of the rectangle is 20cm what is the area of the rectangle?
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
What is area square centimetres of a rectangle with length 7cm and width 5cm?
Multiply the two numbers together - and you get 35 cm2
Is area of a 7 by 8 rectangle?
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
How do you get the area of something?
you times the length by the width, say if a square was 7cm in length and 5cm in width, the area would be 35cm.
What is the area of a trapezoid if the perimeter is 32?
Unlike a square, knowing the perimeter of a trapezoid is not enough to be able to calculate its area. Think of a rectangle with a perimeter of 20cm. One possibility is that it has a length of 8cm and a width of 2cm. This would give and area of 16cm2. However the rectangle could have also had a length of 7cm and a width of 3cm as this would also give a perimeter of 20cm. However this rectangle now has an area of 21cm2. To be able to calculate the area of the trapezoid, you would need to know more about it than just its perimeter.
What is the area of a rectangle with width 7cm and length 9cm?
7cm x 9cm= 63 sq.cms
Rectangle length 7cm width 3cm?
What about it? What is the question?
Find the width of a rectangle if the length is 7cm and perimeter is 35cm?
The width is 10.5 cm.
The length of a rectangle is 4 cm more than the width If the perimeter of the rectangle is 20 cm what are the dimensions?
length + width = 20/2 = 10 length = 7cm, width = 3cm
The length of a rectangle is 4cm longer than the width if the perimeter of the rectangle is 20cm what is the area of the rectangle?
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
What is the area of a rectangle with the sides of 7 cm and 3.5 cm?
The area of a rectangle is calculated by multiplying the length by the width. 7cm x 3.5cm = 24.5 cm2 - cm2 = centimeters squared
What is the fraction of the width of a rectangle if the width is 4cm and the length is 7cm?
It depends on whether you want the width as a fraction of the length or perimeter or something else - like the diagonal.
What is area square centimetres of a rectangle with length 7cm and width 5cm?
Multiply the two numbers together - and you get 35 cm2
What is the perimeter of 7cm by 6cm?
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 ^^
The length of a rectangle is 5 centimeters less than twice it's width The perimeter of the rectangle is 26 cm What are the dimensions of the 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
A rectangle is 7cm wide and 9cm long what is its perimeter?
63 cmPerimeter = 2 x (Length + Width) = 2 x (9cm + 7cm) = 2 x 16cm = 32cm
Is area of a 7 by 8 rectangle?
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
