Question

the length of a rectangle is 8cm and its area is 48cmsquare. find the perimeter of the rectangle ​

Answer 1

Answer:

28cm

Step-by-step explanation:

area=length×breadth

48cm^2=8cm×breadth

breadth=48cm^2/8cm

breadth=6cm

perimeter=2(l+b)

perimeter=2(8+6)cm

perimeter=(2×14)cm

perimeter=28cm

Answer 2

The length of a rectangle is 8cm and its area is 48cmsquare. find the perimeter of the rectangle.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

$\large{\underline{\underline{\bold{\blue{\sf{Answer}}}}}}$

Area=${48cm}^{2}$

Length=8cm.

Breadth= ?

$\large{\underline{\underline{\bold{\green{\sf{Breadth}}}}}}$⇒$\frac{Length}{Area}$

$\large{\underline{\underline{\bold{\orange{\sf{B=}}}}}}$⇒$\frac{8}{48}$

$\cancel\frac{8}{48}=6$

$Perimeter of Rectangle=2(l+b)$

$=2(8+6)$

$=2(14)$

=${28cm}^{2}$
