Rectangles 7346

Draw rectangles. Color them and calculate the circuits and areas.


KLMN: KL = 5CM LM = 3CM

rectangle OPQR OP = 4cm PQ = 3.5cm

Correct answer:

o1 =  16 cm
S1 =  15 cm2
o2 =  15 cm
S2 =  14 cm2

Step-by-step explanation:

a=5 cm b=3 cm o1=2 (a+b)=2 (5+3)=16 cm
S1=a b=5 3=15 cm2
c=4 cm d=3.5 cm o2=2 (c+d)=2 (4+3.5)=15 cm
S2=c d=4 3.5=14 cm2
