Question

Find the missing length of the rectangle below ​

Answer 1

Answer:

The missing side is 15

Step-by-step explanation:

you know that 1 long side is 35 cm so you add 35+35 to get 70

then you subtract 70 fron 100 to get 30

then you divide 30 in 2

Answer 2

Answer:

perimeter of the rectangle=100cm

or. 2(l+b)=100cm

or. 2(35+b)=100cm

or 70+2b=100cm

or. 2b=100cm-70cm

or. 2b=20xm

or. b=20cm/2

. b=10cm

missing length of rectangle=10cm
