Question

Shape a and shape b are each made from four identical sqaures the perimeter of shape a is 56 cm work out shape b

Answer 1

Answer:

44.8 cm

Step-by-step explanation:

Given

See attachment for shapes

$P_A= 56cm$

Required

The perimeter of B

Let the length of a side of the square that makes up A be, l.

So, we have:

$P_A = 10 * l$ --- because A is formed by 10 sides of l

$56 = 10 * l$

$l =\frac{56}{10}$

$l =5.6$

The perimeter of B is:

$p_B = 8*l$ --- because B is formed by 8 sides of l

$p_B = 8*5.6$

$p_B = 44.8$
