Question

lenth of rectriangle is 15 cm and its perimeter is 50 what is its bredth​

Answer 1

Step-by-step explanation:

perimeter=2×(l+b)= 50

2×15+2×b=50

30+2b=50

2b=50-30

2b = 20

b=20/2

b=10

breath =b= 10cm

Answer 2

Answer:

Breadth of the Rectangle is 10 cm.

Step-by-step explanation:

Given :

Length = 15 cm

Perimeter = 50 cm

To find :

The breadth

Solution :

Let the breadth be y

★ $\textsf{Perimeter = 2(Length + Breadth)}$

$\sf{\implies} \:2(15 + y )= 50 \\ \\ \sf{\implies} \:30 + 2y = 50 \\ \\ \sf{\implies} \:2y = 50 - 30 \\ \\ \sf{\implies} \:2y = 20 \\ \\ \sf{\implies} \:y = \dfrac{20}{2} \\ \\ \sf{\implies} \:y = 10$

Breadth = 10 cm

$\therefore$ Breadth of the Rectangle is 10 cm.
