Question

find the breadth and perimeter of rectangle if the length is 15cm and area is 150cm​

Answer 1

Answer:

Step-by-step explanation:

l*b=a

15*b=150

b=150/15

b=10

perimeter=2[l+b]

p=2[15+10]

p=2[25]

p=50

Answer 2

Answer:

Given ,

Length = 15 cm

We know area of triangle = Length × breadth

$\begin{gathered}:\implies\sf{ 15 × breadth = 150cm}\\ \\ \\ :\implies\sf{Breadth = } \dfrac{ 150 } { 15}\\ \\ \\ :\implies\sf{ Breadth = 10cm }\end{gathered}$

Now perimeter :- Perimeter of Rectangle = 2(l + b )

$\begin{gathered}:\implies\sf{ 2( 15 + 10) }\\ \\ \\ :\implies\sf{ 30 + 20}\\ \\ \\ :\implies\sf{ 50cm}\end{gathered}$

Therefore, breadth is 10cm and perimeter is 50cm
