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.
It is: 3*7 = 21cm
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.
area= 7cm x 7cm = 49cm^2
63 cmPerimeter = 2 x (Length + Width) = 2 x (9cm + 7cm) = 2 x 16cm = 32cm
63

24.5 cm sq
It is: 3*7 = 21cm
The area for a 7cm by 8cm is 56.
It is: 4*7 = 28 square 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.
Oh, what a happy little triangle we have here! To find the area, we can use Heron's formula. First, we find the semi-perimeter by adding all three sides and dividing by 2. Then we plug the values into the formula: Area = √(s(s-a)(s-b)(s-c)), where s is the semi-perimeter, a, b, and c are the sides. Happy painting!
The area of a rectangle is calculated by multiplying the length by the width. 7cm x 3.5cm = 24.5 cm2 - cm2 = centimeters squared
24.5 cm2 - Simply multiply the two known values together !
area= 7cm x 7cm = 49cm^2
