P = 2L + 2W
P = 7.6 + 34.6
For an area measuring 4cm long and 3cm wide, the area is equal to 3cm x 4cm = 12 square cm. The perimeter is simply the sum of all the sides, so is equal to 4+4+3+3 = 14cm.
1 meter = 100 centimeters3 meters is equal to 300 cm.Therefore, 3 meters is larger than 200 centimeters.
One foot is equal to 30.48 centimetres. Therefore, 10 feet is equal to 10 x 30.48 = 304.8 centimetres.
To convert centimeters to decameters, you need to divide by 10 twice because there are 10 centimeters in a decimeter and 10 decimeters in a meter. Therefore, 300 cm is equal to 3 decameters (300 cm / 10 cm/dm / 10 dm/m = 3 dam).
we know, Area of rectangle = l X b. area of rect here is equal to ar of square . Hence , area of sq = 7 X 28 . =196 inch sq.
3 cm
it will be 3 cm^2
That's 3 x 8.
The area of a rectangle is calculated by multiplying its length by its width. For a rectangle measuring 3 cm by 9 cm, the area is 3 cm × 9 cm, which equals 27 square centimeters.
The simplest Pythagorean triangle is 3, 4 and 5. Double this gives 6, 8 and 10 so the sides of your rectangle are 6 cm & 8 cm.
To find the area, simply multiply the length times the width. 3 cm x 4 cm = 12 sq cm
Assuming the shape is a 3cm x 8cm rectangle, the area of this shape will be 3 x 8 = 24 cm2 - or 24 square centimetres.
Draw it with dimensions of (6 cm) by (3 cm).
The area of a rectangle is calculated by multiplying its length by its width. For a rectangle measuring 8 cm by 3 cm, the area is 8 cm × 3 cm, which equals 24 square centimeters.
A rectangle measuring 1 by 3 meters has an area of 3 square meters. 1 meter = 100 centimeters 1 square meter = 100 x 100 = 10000 square centimeters. 3 square meters = 30000 square centimeters.
Area = Length * Width = 10*3 = 30 square units.
The perimeter of a rectangle is 2length +2 width. the width is x the length is x+4. Plug into the equation 2(x)+2 (x+4)=20 2x+2x+8=20 4x=12 x=3 The width is 3 the length is 7 (3+4) Area is length times width. 3(7)= 21. the area is 21 centimeters
