A rectangle with sides of 1cm and 6cm has an area of 6 cm2 and a perimeter of 14 cm. A rectangle with sides of 2cm and 3cm has the same area but its perimeter is 10 cm.
length + width = 20/2 = 10 length = 7cm, width = 3cm
Oh, dude, it's like super simple. The area of a rectangle is just the length times the width, so for a 6cm by 3cm rectangle, you just multiply 6 by 3 to get 18 square centimeters. Voilà, math magic!
An isosceles triangle
yeah. a 3cm by 3cm square.
what is the perimeter and area of a rectangle 3cm long and 3cm wide
3cm + 4cm + 3cm + 4cm = 14 cm
16cm.

Perimeter of rectangle: 5+3+5+3 = 16cm
3cm
10cm 2l + 2w 4+6=10cm
The area of rectangle is : 3.0
20cm
It is: 9*3 = 27 square cm
the equation for area is area = length * width. area = 3cm*4cm. Area = 12cm^2
Well, honey, to find the perimeter of a rectangle, you add up all the sides. So for a rectangle with sides of 6cm and 3cm, you add 6 + 6 + 3 + 3, which gives you a perimeter of 18cm. Math doesn't have to be complicated, darling.
