The perimeter of a rectangle is 64cm. Its longest side has a length of 28cm.
State the length of the shortest side.

4cm

Step-by-step explanation:

28 + 28 = 56

64 - 56 = 8

8/2=4

just to check : 4 + 4 + 28 + 28 = 64

hope this helps x

Perimeter of a rectangle = 2(l+b)

2(28+b)=64cm

By using distributive law,

56+2b=64

2b=64-56=8

b=8 divided by 2,4

B=4

Shorter side is 4cm long

answer: no idea

step-by-step explanation: i just want points

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
