area = length x width
area = 12 x 10 = 120 square cm
Perimeter of a rectangle = 2 x length + 2 x width. 52 = 2l + 2 x 12 = 2l + 24 (Where l is the length) 2l = 52 - 24 = 28 length = 28/2 = 14 cm
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.
A rectangle or perhaps a parallelogram
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
To find the area of a rectangle, you multiply its length by its width. In this case, the length is 6 cm and the width is 2 cm. Therefore, the area of the rectangle is 6 cm x 2 cm = 12 square cm.
The area of rectangle is : 72.0
Oh, dude, the area of a rectangle is just the length times the width, so for a 10cm by 12cm rectangle, you just multiply 10 by 12 to get 120 square centimeters. It's like basic math, man, nothing to stress about.
12cm
36 cm2 Area of a rectangle is length times width, so you would multipy 12cm by 3 cm to get 36 sq. (squared) cm.
15 cm Solved through Pythagoras' theorem.
12cm x 12cm
Area = 108cm2 Width = 12cm Length = 9cm
Perimeter of a rectangle = 2 x length + 2 x width. 52 = 2l + 2 x 12 = 2l + 24 (Where l is the length) 2l = 52 - 24 = 28 length = 28/2 = 14 cm
12cm is not uncommon.
5*10*12= 600 cubic centimeter. This is fundamental concept. Request your teacher to 'demonstrate' the same to you.
the equation for area is area = length * width. area = 3cm*4cm. Area = 12cm^2
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.
