Question

Find the height of a rectangle with a base of 8cm and an perimeter of 32cm

Answer 1

Answer:

Height = 8cm

Step-by-step explanation:

$\implies$ $Perimeter=2l+2b$

$\implies$ $32=2l+2(8)$

$\implies$ $32-16=2l$

$\implies$ $16=2l$

$\implies$ ${\Large\frac{16}{2}}=l$

$\implies$ $\large\boxed{l=8\:cm}$

Answer 2

The height of rectangle is 8 cm .

Step-by-step explanation:

Breadth of rectangle = 8 cm

Let Length be x

Perimeter of rectangle = $2(l+b)=2(x+8)$

We are given that  perimeter of 32cm

So, $2(x+8)=32\\x+8=\frac{32}{2}\\x+8=16\\x=16-8\\x=8$

Hence the height of rectangle is 8 cm .
