Assuming the object is a rectangle, the perimeter is (2 x 7cm) + (2 x 10 cm) = 34cm
The answer varies. If by measurement you are seeking the length of the sides, then in whole numbers, the lengths (dimensions) would vary as follows: 1cm x 11cm (1+11+1+11 = 24) 2cm x 10cm 3cm x 9cm 4cm x 8cm 5cm x 7cm 6cm x 6cm
Perimeter = 28 = 4s = 4 x 7 Therefore, each side is 7cm long Area = s x s = 7 x 7 = 49cm squared
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
Area = 1/2 (base x height) If the triangle is sitting on the 9cm side, then 72 = 1/2 ( 9 x height ) Height = 16 cm There are an infinite number of ways to draw the remaining two sides such that the height of the triangle is 16 cm. So the given information doesn't define a unique perimeter.
