To find the area of a regular hexagon with side length of 40cm, consider that since it is regular, then it consists of 6 equilateral triangles of side 40cm. Half of each of those triangles is a right triangle. By the pythagorean theorem, we know that if the hypotenuse is 40cm, and one side is 20cm, then the other side is the square root of (40cm squared - 20cm squared) or about 34.64cm. That makes the area of each of those 12 right triangle to be about 692.8cm, so the total area of the hexagon is about 8313.8cm.

16000 cubic centimeter

160

220 cm2

Multiply the length of the rectangle by the width. For example: 34cm x 20cm = 680cm2

The area of a rectangle is 20 x 50 = 1,000 cm^2

80 meters

The dimensions of the rectangle are 5 cm by 4 cm

Do you mean area or volume - you've included THREE measurements !

25 cm

20cm squared

Answer: 4Area of Rectangle= b x hWorking Out:1. 5cm x 120cm = 600cm22. 10cm x 60cm = 600cm23. 15cm x 40cm = 600cm24. 20cm x 30cm = 600cm2

Answer: 4Area of Rectangle= L x WWorking Out:1. 5cm x 120cm = 600cm22. 10cm x 60cm = 600cm23. 15cm x 40cm = 600cm24. 20cm x 30cm = 600cm2

Area = length * height. A = 20cm * 12cm A = 240 cm2

A 20cm*30cm rectangle has an area of 600 sq cm

First find the dimensions of the rectangle. Let its length be 2x and its width be x: 2(2x+x) = 60 4x+2x = 60 6x = 60 x = 10 Therefore: length = 20cm and the width = 10cm Area = length*width Area = 200cm2

Assuming you meant area of 40 cm2, the rectangle would need to be 40 cm x 1 cm

The formula to find the area of a rectangle is: A = (length)(width)

10cm by 10cm (perimeter=40cm), 5cm by 20cm (perimeter=50cm), 50cm by 2cm (perimeter=104cm), 100cm by 1cm (perimeter=202cm). All of these rectangles' areas are 100cm2

The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.

the length of a rectangle is 5 more then the width. Find the perimeter and the area of the rectangle

Multiply the length and width to find the area of both a rectangle and square.

find the perimeter and area of a rectangle that is 15cm long and 5cm wide

in order to find area of rectangle=(len*bred)
