Question

A rectangle with perimeter 364 cm is divided into seven congruent rectangles

Answer 1

Answer:

perimeter of sided small rectangle= 273/2 cm

perimeter of middle rectngle= 182 cm

Step-by-step explanation:

This is incomplete question. we can calculate perimeter of congruent rectangles. therefore, considering 7 congruent rectangles here is perimeters:

to fit 7 rectangles in rectangle of perimeter, consider x width and 2x length of small rectangles and assume 6 on both sides of rectangle and one in middle from top to bottom.

then,

total perimeter ,

= 2*[(2x+x+2x)+(x+x+x)]

=16x

perimeter= 364 cm

16x= 364

x= 91/4

perimeter of smaller rectangles,

=2* (2x+x)

=6x=273/2

perimeter of middle rectangle,

=2*(3x+x)

=8x= 182
