Ah, what a lovely little rectangle we have here! To find the perimeter, you simply add up all the sides. So for this 7cm by 4cm rectangle, you would add 7 + 7 + 4 + 4 to get a perimeter of 22cm. Isn't that just delightful?
The answer is 28cm
To find the area of a rectangle, you multiply its length by its width. In this case, the length is 7cm and the width is 5cm. So, the area of the rectangle is 7cm x 5cm = 35 square centimeters.
What about it? What is the question?
It is an isosceles triangle with 2 equal sides.
Oh, dude, it's like the area of a rectangle is just the length times the width. So, for this rectangle, you just multiply 7 by 9 and get 63 square centimeters. Easy peasy, lemon squeezy.
4 * 7 = 28 28/2 = 14 sq cm
22 cm
The perimeter is the addition of the all the sides of the shape. For example if a rectangle has two sides which are 4cm and two sides which are 7cm, then the perimeter will be 4cm+4cm+7cm+7cm. The perimeter would therefore be 22cm. The area of a shape is gotten by multiplying the length and breadth of the shape. For example, in a rectangle witrh the same measurements above, the area will be 4cm x 7cm and that would 28cm. You have to use the square sign but I can't do that here.
20cm
Perimeter = 7+7+4+4 = 22 cm
The new dimensions are 4cm and 7cm
It depends on whether you want the width as a fraction of the length or perimeter or something else - like the diagonal.

The ratio is: 7cm to 1cm
Area 51.
To find the area of a rectangle, you multiply its length by its width. In this case, the length is 7cm and the width is 5cm. So, the area of the rectangle is 7cm x 5cm = 35 square centimeters.
A scalene triangle.
The perimeter of a shape is the sum of the lengths of all its sides. In this case, the shape is a rectangle with sides measuring 7cm and 10cm. To find the perimeter, you add up all the sides: 7cm + 7cm + 10cm + 10cm = 34cm. Therefore, the perimeter of this shape is 34cm.
