Question

the length of the rectangle is 18 cm more than its breadth if its perimeter is 136cm find the length and the breadth​

Answer 1

Answer:

Breadth = 25 cm

Length = 43 cm

Step-by-step explanation:

Let us say that Breadth = b

Then, Length = b + 18

2(b + 18 + b) = 136

2b + 18 = 68

2b = 50

b = 25

Breadth = 25 cm

Length = 43 cm

$\blue{★AnsweR⬇⬇}$

Let the breadth be x cm.

Length = (x+18) cm

Perimeter = 136 cm

According to qu.

2(l+b) = 136

2(x+18+x) = 136

2(2x+18) = 136

4x + 36 = 136

4x = 136-36

4x = 100

x = 100/4

x = 25

.°. Breadth = 25 cm

Length = 43 cm
