12cm

area = length x width area = 12 x 10 = 120 square cm

36 cm2 Area of a rectangle is length times width, so you would multipy 12cm by 3 cm to get 36 sq. (squared) cm.

12cm x 12cm

15 cm Solved through Pythagoras' theorem.

12cm is not uncommon.

Area = 108cm2 Width = 12cm Length = 9cm

A rectangle or perhaps a parallelogram

the equation for area is area = length * width. area = 3cm*4cm. Area = 12cm^2

length 14cm, width 2cm This is worked out by finding the following equations: perimeter = 16 x width length = width + 12 Then working out 16 x width = 2 x (width + 12) + 2 x width -> 14 x width = 2 x (width + 12) -> 14 x width = 2 x width + 24 -> 12 x width = 24 -> width = 2cm Since lendth = width + 12, length = 14cm

Answerfirst you have to make it a square by subtracting 2cms from the length and adding 2cms to the width. That will make it equal to 12cm. The area for the rectangle was 140cm then it increased by 4 because 12cm * 12cm is 144cm. so x = 2 and the area increases by four.

the formula for the area of a rectangle is base*width. plug in 2 for the base and 6 for the width. 2*6=12 the answer is 12cm

The area of EVERY rectangle is the product of (length) times (width).Knowing that, you can now find the area of not only that particular rectangle,but also every rectangle you ever encounter for the rest of your life.Man, you are empowered !

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 ^^

what is it

12cm

The area of rectangle is : 48.0

The area of rectangle is : 60.0

The area of rectangle is : 168.0

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

The perimeter of a rectangle is simply the sum of its four sides. In this case - 12 + 19 + 12 + 19 = 62

Area of the rectangle is 144cm. The sides of a square with the same ares is 12cm.

36cm

34cm
