Question

The perimeter of a rectangle card is 28 cm. If the length of the card is 8cm, then find the breath.​

Answer 1

Answer:

length given 8 cm and perimeter 28

then,

perimeter-2×length=bridth

28-16=12/2=6cm ans

Answer 2

Step-by-step explanation:

$\huge{\underline{\underline{Given→}}}$

• $\sf\green{Length\:of\:rectangular\:card=8cm.}$
• $\sf\green{Perimeter\:of\:rectangular\:card=28cm.}$

$\huge{\underline{\underline{To\:Find→}}}$

$\sf\pink{→Breadth\:of\:the\:rectangular\:card.}$

$\huge{\underline{\underline{Answer→}}}$

$→As\:perimeter=2(l+b)$

$→P=2(l+b)$

$→28=2(8+b)$

$→(8+b)=\frac{28}{2}$

$→(8+b)=14$

$→b=14-8$

$→b=6cm.$

$\sf{\boxed{\boxed{\red{→b=6cm✔}}}}$

$→$So breadth of the rectangular card is 6 cm,which is the required answer.
