42mm
That depends on the dimensions !... A 1 x 18 rectangle has a perimeter of 38 ! A 2 x 9 rectangle has a perimeter of 22 ! A 3 x 6 rectangle has a perimeter of 18 !
what is the perimeter of a 11cm x 10cm rectangle answer 42
1cm = 10mm 11mm x 1cm/10mm = 1.1cm
The perimeter of any rectangle is [ 2 x (length + width) ]. Since the length and width of a square are equal, the perimeter of a square is also [ 2 x (side + side) ] = (4 x side).
Perimeter of rectangle = 2 x (length + width) = 2 x (1.6 + 0.8) = 2 x 2.4 = 4.8 meters
The perimeter is the distance around, the sum of the sides. A 5 x 7 or a 4 x 8 rectangle has a perimeter of 24.
width = (x + 4) cm length = [(x + 4) + (x + 7)] cm Rectangle Perimeter = 2[(x + 4) + (x + 4 + x + 7)] cm Rectangle Perimeter = 2[(x + x + x) + (4 + 4 + 7)] cm Rectangle Perimeter = 2(3x + 15) cm Rectangle Perimeter = (6x + 30) cm
That depends. The perimeter of a rectangle equals the all the sides added together! The perimeter of a rectangle is the distance around it. The formula for finding the perimeter of a rectangle is: P = 2L + 2W (the length x 2 added to the width x 2). Example: A 5x10 rectangle has a perimeter of 30: (5x2 + 10x2 = 30)
11mm x 11mm = 121 mm2
2 x base + 2 x height= perimeter
A (114cm x 164cm) rectangle has perimeter of (2 x 114) + (2 x 164) = 556 cm .
perimeter = 2h + 2b ....where h = height and b = base you say that the h = (2b+3) so 2h=2x(2b+3) so substitute that in and we have: perimeter = (2 x (2b +3)) + (2 x b) multiplying out gives perimeter = 4b + 6 + 2b = 6b+6 now we know the perimeter = 72mm = 6b+6 taking the 6 off both sides we get 6b=66mm divide by 6 and we find b=11mm we know h = 2b + 3 and that b=11 so h=22+3=25mm now Area of a rectangle = b x h = 11mm x 25mm = 275mm^2
